Fluke Test Tools: Recommended Battery Testing to Ensure Optimal Uptime

One of the most important parts of every device is its batteries. Professionals in the industry even advise making rounds on batteries to make sure their performance is at a hundred percent. Although batteries today, are evidently more advanced than the ones before and are often tagged as low maintenance, this doesn’t mean that they should be dismissed. Battery testing is one of the musts that every maintenance man/woman should practice. Ultimately, with the help of Fluke test tools, these devices can ensure battery health with a click of a button.

In light of battery kinds, the most popularly used are the uninterrupted power supply (UPS) and battery backup systems. Again, these types of batteries also hold a reputation for being maintenance-free. However, like all things, in time, these batteries are also susceptible to deteriorate over time. Not only that, but they are also prone to corrosion, internal shorts, sulphation, dry out, and seal failure. And when these issues occur, it will result in frustrating downtimes. 

Determining battery failure.

Voltage usually plays a big role in determining battery health. But, the question remains, is it enough? The answer is no. We’re not saying it’s wrong, but you can do more to ensure that your batteries are in a good state.

In totality, measuring voltage is only the tip of the iceberg. Online monitoring equipment or in-person voltage tests won’t give you the full picture of your battery’s health. This is because the voltage is an indication of your battery’s state of charge and not your battery’s health.

To make it clear, the measuring voltage will not tell you beforehand if your battery is degrading. In line with this, voltage testing also has a drawback when a load is applied.

A recommended approach to battery testing.

Instead of relying on voltage testing, try measuring battery impedance as well. In this way, you’ll have a better understanding of the internal resistance of the battery and not just its state of charge. Basically, if you measure battery impedance, this will give you a whole picture of your battery’s issues.

What is battery impedance and why is it preferred?

Battery impedance is made up of two components. Those are electrical and ohmic resistance. Let’s break them down! First, electrical resistance deals with the current flow in an electrical circuit. Meanwhile, ionic resistance measures current flow due to internal factors such as electrode surface area and electrolyte conductivity.

On the other hand, internal ohmic values or also known as the AC resistance can be a big factor in determining the battery’s overall health. AC resistance can be measured by injecting a small current and then later on calculated using Ohm’s law. But in this case, you might want to consider Fluke test tools for easier and more convenient results.

Measuring battery impedance.

Unlike voltage testing, measuring the impedance values can help you detect potential battery problems in advance. In time, a battery’s internal resistance can increase and when this happens, it means that the battery itself is already on the verge of degradation in the cell.     

The best practice for measuring battery impedance. You must be consistent. A single measurement cannot dictate the entire context of what is happening or what is about to happen with your batteries. Make it a habit to measure impedance over months and years. It also helps to examine changes and don’t forget to put it on record every time you make measurements.

Fluke Test Tools: Fluke Battery Analyzer

The best tool to measure battery impedance is none other than Fluke test tools! Specifically, the Fluke Battery Analyzer. This is the ideal fluke test tool for maintenance, troubleshooting, and performance testing of individual stationary batteries and battery banks used in critical battery backup applications.

As we’ve discussed, one of the key points that need to be measured is internal battery resistance, dc and ac voltage, dc and ac current, ripple voltage, frequency, and temperature. With the Fluke Battery Analyzer, you can measure all of these components with just one tool making it a great investment for long-term use!

Fluke Thermometers: How to Get the Best Results!

There is no tool timelier than a Fluke thermometer during the surge of a pandemic. When we are limited to giving physical touch while working, we turn to instruments that can do the job for us. Fluke thermometers are not only supportive of diagnosing technical issues but are also capable of doing thorough temperature reads of different objects. However, this may also vary from the actual object you are measuring.

Recap! A lot of people mistake IR Thermometers for Thermal Imagers. So, what’s the difference? A simple explanation that sets these two fluke devices apart is that Fluke thermometers take an individual number which is the temperature measurement of a single spot on your target. Meanwhile, a thermal camera gives you thermal readings that let you visualize the actual hot and cold spots scenario.

Going back, it’s safe to say that it’s in everyone’s knowledge, Fluke thermometers are great in terms of performance! However, some might not be getting the full experience of these innovative thermometers. This is why we’re telling you how you can get the best results from Fluke thermometers!

Know your IR thermometer’s distance-to-spot ratio

The distance-to-spot ratio is known as the field of view. The field of view plays a critical role in terms of accuracy. This is because the angle of vision it sees will be the average of the temperature it detects.

Additionally, the distance-to-spot ratio also pertains to the size of the area (or spot) being measured. Make sure that the target is larger than the spot size the unit is measuring. The smaller the target, the closer you should be to it. When accuracy is critical, make sure that the target is at least twice as large as the spot size.

Watch out for shiny, “low emissivity” objects.

Yes, shiny objects have the tendency to bewilder your IR gun which as a result can give inaccurate results. According to EnnoLogic, IR thermometers are pre-set at an emissivity of 0.95.  However, objects with much lower emissivity ratings, such as polished metal, will give false temperature readings.

Another source from Thermo Works stated that most organic materials, including the by-products of plants and animals, have an emissivity rating of 0.95. In return, these are the ideal surfaces to point at if you want accurate results. Meanwhile, polished metals and other shiny things are known to have very low emissivity levels since they tend to be very reflective of ambient infrared energy.

Steam or dust can affect the accuracy of IR thermometers.

Remember that these elements can confuse readings for the simple reason that they blur the lens. Naturally, blurry lenses can result in inaccurate readings for infrared thermometers. Think of it this way, if you look through a camera with blurred lenses or steam, those elements will show in the photos. Therefore, before shooting your IR gun, always make sure to wipe the lenses with appropriate tools to better its reading process.

Avoid temperature-shocking your infrared thermometer.

We know that Fluke is known for its excellence of being the most versatile test tool in the market, and it’s not wrong. However, some of its tools are also quite sensitive depending on their usage. Nevertheless, don’t mistake this aspect as a weak spot since this does not dampen its high-performing nature.

Letting your Fluke thermometer simmer in its surroundings can ultimately grant you more chances to get accurate readings. Give your thermometer at least 20 minutes to bask in its given environment. For example, you’ve just only done temperature checks in a cold room and then moved on to a much warmer area. Immediately putting your device on the spot might not get you the most “spot-on” results, instead, let it sit and take in the surrounding for a minimum of 20 minutes.

Fluke Insulation Testers: How To Choose The Best One That Fits Your Needs

It’s a handy thing to have Fluke insulation testers at the back pocket of every maintenance or troubleshooting professional. However, are you sure that it’s the right insulation tester to get the job done?  Insulation testers are known to be a popular tool for machinery that prevents faults from occurring. It has the advanced capability of detecting machine imperfections ahead of time and this, ultimately, makes it an ideal tool for your voltage and current measurement needs.

 

Importance of insulation testing.

Are you familiar with pipe leaks? Or how about a balloon with a needle puncture? The bottom line is, both of these minor malfunctions have one thing in common. With pipe leaks, a bit of water will be dripping out (depending on how big the puncture is). On the other hand, with the punctured balloon, the small puncture will cause it to deflate little by little and lose its overall capacity to be in good working condition.

 

Basically, this is also what happens to wires. Although from the outside, a wire seems well protected, one shouldn’t be too sure. Wires contain currents. And at times, these currents don’t always flow perfectly. Sometimes, steady flows of energy can stray away from a perfect line.

 

Which leads us to the next question, how do we detect these malfunctions caused by the current? This is where insulation testers come into the picture.

 

Types of currents to watch out for.

Knowing the type of energy that flows into the wires you’re testing for also proves significance. Here, you’ll get to know three kinds of currents which are capacitive currents, absorption current, and leakage current. Let’s get to know each one up close.

 

  1. Capacitive currents – It is the process of collecting and storing energy from an electrical charge. Capacitors come in many forms. Energy storing devices are one of their popular reputations.

 

  1. Absorption current – Absorption current takes place when voltage builds up. Ultimately, when voltage goes to an all-time high, the insulation decreases. In return, this will create a gradual change that will reflect its storage of potential energy along with the insulation.

 

  1. Leakage current –  A number one case scenario of deteriorating insulation is a leakage in the currents. Additionally, this is also a result of a decrease in resistance.

 

 

Significant uses of Fluke Insulation Testers.

Insulation testers are particularly important to be used when new electrical machinery is being installed. This is to make certain that insulations are in good shape. Take note that testing should come before the installation. Using insulation testers before any operation is for the good of the machines and for the safety of personnel.

 

Furthermore, one of the most notable features of Fluke insulation testers is that they can download data for future reference testing. This is advantageous for maintenance professionals since this kind of feature saves time and saves us the hassle to keep documentation from every testing.

The Perfect Tool to Maintain and Improve Indoor Air Quality in Healthcare Centers

Monitoring air quality and assessing the level of contaminants in the air is not only important to all healthcare centers, but also in places we usually frequent. These places are shopping malls, schools, homes, hospitals, etc. We may not pay attention to it from time to time, but the air we breathe holds either positive or negative effects on our quality of life.

In light of hospitals and health care centers, it is a crucial aspect for them to have clean air for the benefit of injured patients, critical patients, or even visitors. Healthcare centers or hospitals should exude safety and cleanliness and this entails comfortable breathing grounds for visitors and patients. Thanks to technology, it is now achievable to monitor and maintain clean air. The best device to ensure quality air is with the use of the Fluke 985 Particle Counter. Let’s take a closer look, shall we?

Why is air quality so important in healthcare facilities?

The air we breathe goes directly to our lungs. This is a leeway for the air to also access our bloodstream and be carried to our internal organs. Therefore, inhaling air pollutants (whether indoor or outdoor) can be a result of health concerns such as asthma, cardiovascular diseases, or even cancer. 

In healthcare facilities, there are patients that are highly sensitive to bacteria. The smallest exposure can cause some patients disastrous health effects. This is why maintaining clean air inside hospitals and healthcare facilities is one of the top priorities of maintenance professionals. 

Impact of poor air quality in healthcare centers

Something that cannot be seen does not mean that it should be dismissed. It is undeniable that air makes a big impact on a person’s health. Maintaining air quality is an important aspect in places we usually visit. In light of healthcare centers, indoor air quality can either enhance a patient’s health or cause it to worsen one’s condition. We might not notice it immediately, but here are some of the health issues that come with harmful air contaminants.

Poor air quality can cause people:

  • Eye irritation 
  • Raspy throats
  • Headache
  • Nausea
  • May increase fatigue
  • Shortness of breath
  • Might inflame people with asthma
  • Can aggravate respiratory conditions 
  • It affects the heart and cardiovascular system
  • Wheezing
  • Coughing

Effects of good air quality in healthcare centers

On the other hand, there are benefits of breathing good quality air. Good air can result in remarkable health effects for people. According to Transport and Environment, a person inhales 15,000 liters of air every day. Think of it this way, if you are breathing bad quality air, that’s 15,000 liters of inhaling pollutants a day. That alone can cause serious damage to our bodies. Meanwhile breathing 15 thousand liters of clean air can result in a better quality of life. 

Breathing good quality air entails:

  • Good for digestive systems
  • Improves blood pressure
  • Improves heart rate
  • Strengthens your immune system 
  • Healthier for the lungs
  • Enhances your energy levels
  • Improves mental health and focus
  • Enhances your mood

Beating indoor air contaminants

In totality, it can pose as a difficult task to contain harmful airborne contaminants in a healthcare facility. But how do you beat something that you cannot see? How do you contain something that lives in the air we breathe? The first step to take is to actually detect these air impurities.  This is where the work of innovative technologies comes in. Fluke 985 Particle Counter can assess these air contaminants making it easier and more efficient for maintenance professionals to plan their next more. 

Things you can do to improve air quality in enclosed spaces

Having devices that help you maintain air quality such as the Fluke 985 Particle Counter is one thing, but you also need to take action to actually gain quality air. 

Here are some things you can do:

  • AC Filters – Don’t dismiss your AC filters. They are one of the most common appliances at home, in the office, or even in buildings and establishments. Filters can become dirty and dustier in time when not cleaned and this could cause poor air quality performance. If you clean these filters, you’ll notice that the air conditioning will blow much cooler air. 
  • Every filter counts  – AC filters are only one part, but if you really want to improve the air quality, every appliance that has filters should be changed. This includes coffee filters, vacuum filters, clothes dryers, etc. These appliances’ filters are advisable to be changed at least once every month.
  • Cooking vents – Most pollutants usually come from the kitchen especially when you’re using gas stoves. Gas stoves can release toxic contaminants, including carbon monoxide and nitrogen dioxide. So it’s important to keep in mind to open windows, or air vents when cooking. If you’re cooking in an outdoor setting, then that’s much better to keep contaminants out of enclosed spaces.
  • Hospital vents – Installing High-Efficiency Particulate Air Filters (HEPA) can improve the movement of air particles. This can help contain infectious air particles.
  • Rugs and carpets – They contain the most dust particles when not cleaned. And these dust particles tend to stick to the air. Not cleaning rugs and carpets might irritate our senses and this will cause uncomfortability for you or for patients and other visitors. This is why healthcare centers (if you notice) do not have many rugs and carpets because they are a known holder of air contaminants.
  • Indoor plants – Having plants can help improve air quality in any space. Plants are natural air filters. They can improve the air you breathe, and at the same time, enhance the aesthetics of your homes, office, or spaces in general.

How to Spot Mechanical Failures in Advance with Vibration Testers?

How often do we identify its underlying deficiencies? Sometimes we almost don’t notice it at all. We just know the moment when it actually breaks down. But what if you can actually detect these mechanical failures in advance? In this way, you could immediately fix the damaged part of the machinery and save time. Luckily, the Fluke 810 Vibration Tester can provide easy and accurate electrical motor readings.

 

Spotting mechanical failures in advance

Waiting for these machines to actually break down before fixing it will undoubtedly be more costly. However, spotting minor deficiencies before it gets bigger will be more beneficial to maintain the longevity of the machine. Looking at an electrical motor, you would think that this huge piece of metal that helps make things run is a total buff guy. To tell you the truth, these motors are actually more sensitive than meets the eye. Moreover, there are a lot of factors contributing to their decay and deficiencies.

 

  • Put them in the right temperature – Temperatures are an important element for an electrical motor to gain longevity. This is why they are mostly stored in places wherein temperatures can be balanced. Not too hot, and not too cold. 

 

  • They are sensitive to dust and contaminants – This is another reason why electrical motors are stored in closed places. This is to prevent them from being exposed to dust and other contaminants.

 

  • Power surges – This is because some motors draw more power than they can handle. This can cause power surges and supply issues.

 

  • Moisture and humidity exposure is a no-no! – Electrical motors that are constantly being exposed to moisture and humidity can shorten a motor’s life.

 

  • Lubricating the motor is easier said than done – Mechanical engineers with experience are usually tasked to lubricate engines. This is also one of the sensitive parts of the machine since the right balance of lubrication is needed. Too much lubrication will be bad and less lubrication will not suffice as well.

Fluke’s FoodPro Plus is a Must-Have for All Food Service Professionals

Good food is even better if it guarantees good quality! A lot of excellent food service professionals take extra precautions and safety measures to ensure that their product is in its best shape. One of the precautionary measures they carry out is doing fast and accurate temperature monitoring. Temperature monitoring is done from the moment you receive the frozen goods, all the way to it being cooked and served to its consumers. 

On the other hand, from a consumers’ point of view, more often than not, we don’t even bother noticing the temperature of the food we are about to eat. However, giving light to temperature importance, our foodservice professionals make it a habit to observe the proper coldness of our food, and proper heating as well. This is where Fluke’s FoodPro Plus comes in handy. 

Why is food temperature important? 

Let’s take meat for example. This is common knowledge to all foodservice professionals. According to the U.S Department of Agriculture, proper cold temperatures will reduce the growth of microorganisms and harmful toxins. Moreover, this will also protect the meat from bacterial growth and prevent it from getting molds. 

Meat is a good example of temperature checking. In such circumstances that they are not chilled or heated properly, it will result in disastrous effects. On the flip side, cooked meat also needs reassurance of a good temperature. A temperature of 75 °C must be reached to ensure all food poisoning bacteria are gone. 

Fluke’s FoodPro Plus is a Must-Have!

The FoodPro Plus is the complete solution to measure the proper coldness or hotness of the food. Fluke’s FoodPro Plus is the new must-have to ensure food safety.

Fluke Digital Multimeters: Using Current Clamps On Multimeters

Accessory current clamps can expand a multimeter’s flexibility and measurement capabilities by allowing it to measure up to thousands of amps. The clamp accessory reduces the actual measured current by a fixed ratio. This means that the current maximum is now limited by the clamp instead of the multimeter.

The following discussion focuses on the most common types of current clamps used with digital multimeters (Digital multimeter):

  1. AC only with a milliamp output like the Fluke i200, i400, 80i-400, 80i-600A or i800
  2. AC/DC with a millivolt output like the Fluke i410 AC/DC Current Clamp AC/DC Current Clamp, i1010 and 80i-110s

Note: This is not a complete user guide. Make sure to read the safety and usage information contained within the clamp’s instruction sheets.

AC clamps: Fluke i200, i400, 80i-400 or i800

The i200, i400, 80i-400, and i800 are current transformer-type clamps that have an output of 1 milliamp ac per amp ac. This is a 1000:1 ratio. Additionally, they also have banana plug connections. However, take note that these clamps do not measure dc current.

To use these clamps with a Fluke Digital multimeter, the meter must have a milliamp input jack. Plug the black output lead into the meter’s common jack and the red output lead into the meter’s milliamp or mA input jack. Set the meter’s function switch to read ac milliamps.

Furthermore, place the clamp jaws around only one conductor of the circuit. Clamping around both the line and neutral conductors (like a line cord) at the same time will cancel the current flow reading. If there is currently flowing in the circuit, the milliamp reading in the display will be the actual current flow in amps.

The reading on the Fluke 87V Industrial Multimeter display (15.86 mA ac) corresponds to a true circuit current of 15.86 amps ac. The reading on the Fluke 289 True-RMS Data Logging Multimeter display (225.32 mA ac) corresponds to a true circuit current of 225.32 amps ac.

AC/DC clamps: Fluke i410 AC/DC Current Clamp AC/DC Current Clamp and i1010

The i410 and i1010 are ac/dc Hall Effect type clamps. That is, they contain Hall Effect sensors, and have internal electronics and a power switch. These clamps have an output of 1 millivolt ac per amp ac for ac current measurements and 1 millivolt dc per amp dc for dc current measurements. Again, these have a 1000:1 turns ratio.

To use these clamps with a Fluke Digital multimeter for best results, the meter should have a millivolt range for either ac or dc voltage depending on the current to be measured. And then, there are ac current measurements. For this to work, plug the black output lead into the meter’s common jack and the red output lead into the meter’s V/? input jack. Set the meter’s function switch to read ac voltage or ac millivolts.

Connections for i410/i1010 clamps with a 289 Digital multimeter

The reading in the Fluke 289 True-RMS Data Logging Multimeter display (7.437 mV ac) corresponds to a true circuit current of 7.437 amps ac.

For dc current measurements, here’s what you have to do. Plug the black output lead into the meter’s common jack and the red output lead into the meter’s V/? input jack. Set the meter’s function switch to read dc millivolts. Turn the clamp on by pressing the green power button.

Here’s what you should do for the most accurate dc measurements. With the jaws closed use the “zero” adjust to zero the displayed reading before clamping around the current to be measured. DC measurements only require zero adjustments. Only one conductor should have clamp jaws wrapped around them. If there is currently flowing in the circuit, the millivolt reading in the display will be the actual current flow in amps.

AC/DC clamps: Fluke 80i-110s

80i-110s is also an ac/dc Hall Effect Type clamp. This is a dual-range clamp with an output of either 10 millivolts or 100 millivolts per amp ac for ac current measurements or 10 millivolts or 100 millivolts per amp dc for dc current measurements. Use the 100 millivolts per amp position for accurate current measurements up to 10 amps and the 10 millivolts per amp position for current measurements exceeding 10 amps but less than 100 amps

initially, this clamp was originally designed for use with an oscilloscope and terminates with a BNC-style connector. To use it with a Digital multimeter, add a PM9081/001 BNC to the dual banana adapter. Therefore, for best results, the Digital multimeter should have a millivolt range for either ac or dc voltage, depending on the current to be measured.

Meanwhile, for ac current measurements, plug the black output connector into the meter’s common jack and the red output connector into the meter’s V/? input jack. Set the meter’s function switch to read AC millivolts or AC voltage. Finally, turn the probe on by sliding the switch from “Off” to the appropriate range position depending on the current.

How To Track Intermittent Faults In Overhead Utility Cables?

Intermittent faults are notoriously hard to find. If you don’t know when they’ll occur, you need some form of data logging. To put it simply, intermittent faults are malfunctions of devices or systems caused in intervals. In addition to this, you may also need to transfer the data remotely. So, measuring instruments should be versatile and intelligent with a Wi-Fi connection, and may need to read two external sensors.

Intermittent Faults: Overhead and underground utility cables

One of the users is an energy utility with extensive overhead and underground cables. Like the vast majority of energy utilities, they need to know the overhead cable power quality. Alongside the faults found in any other network, these are very sensitive to all kinds of weather phenomena.

Moreover, strong winds can cause wires to “gallop” and touch each other. That can cause voltage dips or short interruptions. Wires can then or at other times touch trees which can cause flashovers or even fires. Pylons can blow down, broken branches can damage cables, and driving rain or hail can penetrate electrical joints.

This utility’s end customer was complaining of flickers and voltage fluctuations. The maintenance department measured power quality parameters on the overhead power lines. Crucial measurements because these parameters give you some of the most important top-level fault-finding information.

Intermittent Faults: Excessive flicker and voltage dips

The measurements verified that flicker and voltage dips exceeded EN50160 limits, but the cause was not clear. One possibility was the wind making tree branches either touch the wires or shake a wire loose at a poor connector. Your first thought might be to send someone out to check, but long lines are expensive to test that way. Then again, a windy environment is ideal for measurements like this. This is because whether a branch hits the line (for example) will depend not only on the clearance but also on the stiffness or flexibility of the tree.

Our Fluke 1748 three-phase power quality logger monitored the wind speed across an anemometer. Importantly for energy utilities, 1748 complies fully with the 3rd edition of the IEC61000-4-30 standard. The logger captures voltage, current, power, energy, frequency, and power factor. It quickly assesses power quality to standards like EN 50160 and IEEE 519. The instrument is rated at 600 V CAT IV/1000 V CAT III for service entrance, substations, and downstream. It stores more than 20 separate logging sessions, and can quickly create reports to confirm the findings.

A Kirwan INT10 BA® anemometer was fixed to the top of a 230-V supply pole, supplied by the battery to ensure uninterrupted power.

The Fluke 1748 was fitted with a 174x AUX accessory that accepts two inputs, one between ± 10V DC and the other between ± 1,000V DC. The AUX inputs can be freely scaled in software, and the signals can be correlated to each other. That was key for this application and is virtually unique to 1748. The first input was attached to the anemometer, which converts wind speeds of 0 to 60 m/s to a linear output signal of 0 to 10 V. The second monitored the overhead cable voltage.

The instrument software allowed the utility to analyze the results immediately and download the data to a laptop 10 meters away without interrupting data logging. A month’s worth of measurements correlated voltage variations and wind speed. That confirmed the fault caused to be galloping wires, and the problem was quickly found to be worn wire connectors.

Repayment times

Repayment time is possibly the single most important measure of an instrument’s value to our customers. In cases like this, though, it’s difficult to assess: how do you value your customers’ goodwill and how they feel about your service? Let alone the work satisfaction and reputation of a fault quickly solved by your maintenance department.

Electrical Transmission Cables

  • Measuring tools: Fluke 1587 Insulation Multimeter
  • Operator: Singapore electrical utility
  • Tests conducted: Insulation resistance cable test, continuity, voltage

When the electrical transmission is underway and distributed from generation plants to the end-users, it passes through numerous sections of low voltage and high voltage cables. These transmission cables are also used to connect to the secondary outputs of current transformers (CT). They are deployed at both ends of the transmission stations, also known as sub-stations. The Fluke 1587 Insulation Multimeter is the direct action to any electrical transmission cables’ faulty wirings.

To protect critical equipment and prevent the escalation of faults, these pilot cables serve to detect any unbalances between the corresponding pairs of CT. Ultimately, this may affect the entire transmission network. While only one pair of wires is needed to complete the connections, operation, and redundancy, planning calls for a minimum of three functional pairs of wires at any one time.

About electrical transmission.

It is impossible to have a single cable that spans the vast distance between sub-stations. As a result, this can imply a connection of cables. To say the least, such joints are the weakest links in the system. Ultimately, environmental factors can cause faulty joints. One of these factors includes thermal stress and moisture absorption. The failures will show up when current readings taken at the secondary of CT deviate from the proportional primary current readings. Remember, never be complacent with these kinds of abnormalities so it’s always safe to contact someone who knows their way around. Call utility maintenance when these kinds of faults occur.

Meanwhile, maintenance men have to travel to the sub-station at one end to isolate the affected CT and pilot cable at that sub-station. Then they need to travel to the sub-station at the other end to check the insulation resistance of the pilot cable.

While they’re at it, they will check the pair of wires that have been used, as well as all the remaining 4 or 9 pairs of wires in the same bunch of pilot cable, and ensure at least three pairs are functional. As some wires may have permanent damage, there’s actually a way to prevent this. How? With the use of colored cables. Different colored wires are mixed to achieve a minimum of 3 functional pairs. Therefore, the team must verify the exact inter-connect pairs and they term this work as “phasing”.

Thereafter, to prevent abnormality, make it a habit to check insulation resistance. This also goes for “phasing”.

Remember…

In addition, these tests can be mandated by a new extension of cables due to civil engineering works. It’s no secret that time is critical for maintenance men, so the faster the troubleshooting, the better. Moreover, doing these tests in the shortest time possible is a huge plus. Maintenance people find the Fluke 1587 Insulation Multimeter a very versatile tool. Why? This device can perform insulation resistance tests as well as voltage measurements and continuity checks.

For testing of high voltage equipment, cables and switchgear, the team relied on the Fluke 1550B 5 VK MegOhmMeter.

Thermal Imaging Software: Choose The One That Makes Your Job Easier!

Thermal imaging software extends a lot more features and happens a lot easier to utilize than what was accessible in the past. Now, you can connect thermal imaging software on a PC or mobile device. Ultimately, this can establish, improve, simplify, and evaluate images and construct professional-looking reports that you can distribute in email.

Moreover, don’t think that by augmenting images you’re altering the actual data; you’re just modifying how it is presented so that even an inexperienced eye can clearly see anomalies. Basically, this helps expedite decisions and minimize debates.

Choosing Thermal Imagers…

Here are some of the basic rules for choosing thermal imaging software is to make sure it allows you to:

  • Process and export images in multiple formats including .jpg, .tiff, .bmp, .gif, and .avi as well as proprietary formats that allow you to access more data for advanced analysis.
  • Edit and manipulate images by adjusting level and span, changing emissivity, adding markers, highlighting hot spots, referencing images, and applying color alarms.
  • Combine visible light and infrared images and adjust the blend between the two to more easily locate and highlight potential problem areas.
  • View and share images live from your camera, your smartphone, or your computer to collaborate with remote team members.
  • Remotely control your infrared camera to adjust focus or capture images without touching the camera. This is especially valuable in potentially hazardous areas or tight spaces.
  • Create templated or custom reports that you can share in .pdf or .docx formats.
  • Perform three-dimensional analysis so you can view infrared images from multiple perspectives to identify additional problem areas and help eliminate false positives.
  • Compare images side-by-side so you can see the changes in the same target over time to aid predictive maintenance programs.
  • Change color palette to make hot or cold areas more obvious with high contrast palettes or to see subtler differences with a grayscale palette.
  • Add text and audio annotations along with additional visible-light images to provide the details you need for thorough reporting.
  • Categorize, catalog, or tag images and associate them with equipment to make it easier to track images over time.
