battery and backup power testing

The Importance of Battery and Backup Power Testing

There’s no doubt that a backup power system is one of the most important things an engineer must consider when working on high performance buildings and industries such as hotels, hospitals, data centers and industrial factories. Backup power testing is indeed important to make sure that backup power systems work.

 

It is imperative for companies in these industries to have uninterruptible power supply (UPS) and batteries in cases when external generation sources are unavailable to provide safety and protection for assets that may be lost during power outages. Thus, battery testing plays a crucial role in power system preparedness.

 

Take the following into careful consideration when testing your batteries:

 

  • Speed
  • Fast and easy reporting
  • Easy data capture
  • Easy reporting
  • Limiting human errors when making measurements on large strings

step by step approach to troubleshooting

A Step-by-step Approach to System Troubleshooting

Troubleshooting is a process in which devices or systems are repaired. Step-by-step procedures are followed in order to quickly identify and repair issues. There are various test instruments help you through the repair process. Here’s a simple step-by-step run through of what you need to be doing:

 

  1. Start by collecting technical records from relevant sources.

 

Knowing what kind of situation you are dealing with is vital in every repair situation. Analyze the scenario by gathering information from the original equipment manufacturer, suppliers, contractors, operators, and maintenance departments.

  1. Isolate the part of the system or equipment to be tested

 

Gather your test instruments and personal protective equipment before you start the testing process.

 

  1. Take note of all readings

 

Take readings on this portion to test for malfunctions. You might need to test for multiple readings to identify proper operation and the problem at hand.

 

  1. Identify problem and Recommend Repair Actions

 

After doing rigorous tests, you should be able to identify the cause of the problem. Give out suggestions for repairs such as parts replacement, system updating, technical service, or redemption of warranty.

 

  1. Documentation

 

Once all repairs are completed, make sure that you document all changes and repairs that were made. This is so you have something to refer to the next time something happens with the device or system. In this step, you may also include suggestions to improve its performance.

 

However, even though the repair process can be compressed into 5 simple steps, the extensiveness of a repair work can range as broad as a building repair or as specific as an individual component. To avoid unexpected repairs, basic tests on devices and systems should be done regularly so you are able to forecast device or system performances. The most common basic mandatory tests are Voltage and Current test, they are also, typically, the first tests conducted at easily accessible points of measurement or access.

 

If you are looking for Voltage and Current test Equipment, you might want to check out the Fluke 773 Milliamp Process Clamp Meter, it is known to have a 0.2% accuracy and delivers a 0.01 mA resolution and sensitivity.

AC voltage sensors

Knowing more about capacitive voltage sensors

Ever imagined how capacitive voltage sensors work?

 

AC voltage detectors’ functions are based on the principle of capacitive coupling. According to Fluke, to understand this, let’s return momentarily to the Electrical Circuit Theory and recall how a capacitor works. A capacitor has two conductors or ‘plates’ that are separated by a non-conductor called a dielectric. If we connect an AC voltage across the two conductors, AC current will flow through as the electrons are alternately attracted or repelled by the voltage on the opposite plate. The AC circuit can still be complete even without the occurrence of a hard-wired circuit connection. Given that the electrical field inside the capacitor, between the two plates, is what completes the AC circuit.

 

We are simply missing the fact that our world is full of small stray capacitors with the thinking that these are just individual circuit components functioning like motor starting caps.

 

Here’s an example from the Fluke website:

 

Suppose you are standing on a carpeted concrete floor directly under a 120 V light fixture and the light is on. Your body is conducting a small AC current as it becomes part of a circuit consisting of two capacitors in series. The two conductors or plates for the first capacitor are the live element in the light bulb and your body. The dielectric is the air (and maybe your hat) between them.

 

The two conductors for the second capacitor are your body and the concrete floor (remember that concrete is a good conductor, as is shown by using concrete encased electrodes as earth grounds). The dielectric for the second capacitor is the carpet plus your shoes and socks. This second capacitor is much larger than the first. AC current will manage to flow because of the 120 V across the series combination. (This current must be way below the shock threshold, or we wouldn’t be living in a world of AC power – we definitely would not be turning on lights in the bathroom.)

clamp meters

Everything You Need to Know About Clamp Meters

Every trade has its own set of equipment. While many manual professions use standard tools like screwdrivers, pliers, and drills, specialized occupations like electricians need more advanced tools tailored for the job. Even the most skilled electricians depend on these tools to do their jobs properly and more effectively.

 

Today they face more challenges due to technological advances of electrical equipment and circuits, though these were made to make work easier, more training is now needed for its proper utilization. These advances require a higher skill level for those who would be using them, as well as more advanced testing procedures. Enough knowledge and understanding of proper test equipment use will be beneficial in handling testing and troubleshooting issues. One of the most commonly used equipment by electricians and technicians for similar situations is the clamp meter.

 

What is a Clamp Meter?

A clamp meter is an energy management tool that combines a voltmeter with a clamp-type current meter. In analogy, it is basically a current-measuring tool with some voltage abilities. The clamp meter was created primarily as a single purpose test tool for electricians; however, today’s modern models have integrated more measurement functions, accuracy, and other special features.

 

Advantages of Using a Clamp Meter

When it comes to testing plants or all sorts of machinery, an electrical tester like the clamp meter is the best choice. One of the advantages of using a clamp meter over digital multimeters is that you can measure the electric current passing through a device without breaking any circuits.

 

Effective troubleshooting often requires two readers – one to measure voltage, and the other to measure electrical current. Most electricians consider a clamp meter to be one of the most versatile diagnostic tools as it can do both.

 

Choosing the Right Clamp Meter

There are a few factors to consider when buying a clamp meter. Apart from looking at its specifications, one should also consider its features, functions, and overall quality of the production of the device.

 

Obviously, User Safety proves to be a necessity given that this profession handles many hazards. The device must adhere to the latest electrical standards and should be certified by testing labs such as UL, CSA, and VDE among others. Certifications assure you that the electrical tester meets all safety standards.

 

Given the nature of where the device will be used, a clamp meter must also be able to withstand tough conditions. The tool needs to be reliable. Luckily, the Fluke Clamp Meters are carefully designed to be electrically and mechanically robust. By the time they’re ready to be used, you’ll be sure they’ve undergone rigorous testing and evaluation.

battery back up systems

Recommended Battery Tests for Battery Backup Systems

Batteries are perhaps one of the things that most people take for granted. Batteries are easily disposable, and you can get them almost anywhere. But disposable as they may be, we should learn how to take care of them. Be wary of the battery and equipment checkup dates to extend the lifespan of our equipment.

A healthy battery should maintain a capacity above 90% of the manufacturer’s rating; if it falls below 80%, then most manufacturers would recommend a replacement. Conduct a series of regular testing to ensure that batteries are maintaining capacity. Here are some indicators to watch out to know if you’re batteries are up for replacement.

  • There is a drop in capacity of more than 10% compared to benchmark or previous measurement.
  • 20% or more increase in resistance compared to benchmark or previous measurement.
  • Sustained high temperature
  • Degradation in plate condition.

There is an institute called, The Institute of Electronic and Electrical Engineers (IEEE) wherein they’ve recommended a combination of tests to perform. If you want to know more about this, you may check it out here.

pressure switch testing manual approach

Manual approach to pressure switch testing

Determining accurate calibration of pressure switches is an essential method to ensure quality and safe operation of the equipment. It is similar to pressure gauge calibration which measures voltage or continuity across a set of switch contacts through (Digital Multimeter) DMM or a calibrator. It is important to know that the purpose of calibration is to detect and correct errors in the set point and dead band of the pressure switch. It helps save time and processes as it reduces the amount of equipment needed for a calibration job. Having the right calibration tools can enable many technicians’ work to be automated.

To perform the test:

Setup

  1. Make sure to safely disconnect the device from the process it controls.
  2. Connect the calibrator or DMM to the common and NO (normally open) output terminals of the switch. This process should measure an “open circuit” for continuity. If, however, you are measuring V ac be sure the tool is properly rated towards the voltage that is being measured.
  3. Connect the pressure switch to a pressure source such as a hand pump that can be connected to a gauge.

Rising pressure

  1. Increase the source pressure to the set point of the switch until the switch changes state from open to close. Manually record the pressure value when the DMM indicates a “short circuit”. If you are using a calibrator, it should record the value for you.

Falling pressure

  1. Continue to increase the pressure until you reach the maximum rated pressure. Slowly reduce the pressure until the switch changes state again, and resets from closed to open, then record the pressure.

Calculation

  1. The set point pressure should be recorded when the pressure was rising. The dead band value is the difference between the rising set point pressure and the falling pressure reset point.

Every mechanical and electrical work that requires pressure devices should be carefully tested. It is significant in order to have a safe and high-quality work procedures. Having the right calibration tools will not just ensure the safety of those who will use the device but also ensure convenience and efficiency. If you are looking for a significant and reliable calibration tools, Presidium.ph Corporation is the one that you might want to consider.

infrared thermography

Infrared Thermography: Explained

Machine failure don’t just happen in an instant. Most machine failures – whether its electrical, mechanical, process, or electronic- begins with a significant increase in operating temperature even before the problem occurs. Machine failure is usually like running out of your battery car. There’s no way to tell when you will run out of battery, one day your car just won’t start. Fortunately for machineries, there are devices that can detect and determine if there is an unusual heat activity that can possibly cause problems to your machine.

An Infrared Thermography can detect infrared energy emitted by an object, converting it to apparent temperature, and displaying the result as an infrared image. Infrared thermography came from the literal meaning “beyond red” (infrared) and “temperature picture” (thermography).

Why get an infrared camera?

An infrared camera allows you to capture thermal images without making direct contact with the equipment. That means you can capture thermal information from operating equipment at a safe distance and have a better chance of seeing temperature anomalies under normal operating conditions. Widely popular infrared cameras capture radiometric thermal images that contain apparent temperature measurements for each pixel within the image. This capability allows you to identify an anomaly and then drill down to calculate the apparent temperate of the points in question.

Big Benefit

The non-contact feature of infrared technology makes it ideal for a wide range of applications where components are moving, very hot, dangerous to contact, difficult to reach, impossible to shut off, or could be contaminated or damaged through contact. Infrared cameras are also helpful in detecting energy or moisture-related issues in a building envelope.

Unlike older thermal imagers that were larger, more expensive, slower, and poorer image resolution, newer versions of thermal imagers perform much better. They are more compact, with ergonomic cameras that are easy and fast to use, and they are much more affordable with high resolution images. With the help of these new thermal imagers, now it is speedier and convenient to conduct inspections and fix machinery issues that you may have overlooked.

If you’re looking for the best-performing thermal imager in the country, Presidium.PH has got it for you. You may reach them at +632 464 9339 or email them at info@presidium.ph.

thermal imager benefits

Benefits of Using Thermal Imagers

Thermal imagers, also known as infrared cameras, allow technicians to detect issues before they cause bigger problems or failures. While some equipment present obvious symptoms through unusual vibration or sounds, other electrical problems may only be detected by thermal patterns. It’s important to identify these issues before they lead to equipment failure or serious electrical hazards.

Infrared thermography offers a wide variety of advantages. It can speed up diagnosis, reduce – and possible even avoid – unscheduled downtime, and minimize damage to structure and contents.

Here are the various use of thermal imagers:

  • Most types of equipment
  • Collecting data in hazardous environments from a safe distance
  • Scanning large areas such as walls, ceilings, and roofs quickly
  • Gathering data without disrupting production
  • Quickly identifying irregularities in specific locations
  • Detecting problems before failure

These advantages not only help technicians and contractors, but also produce additional benefits for troubleshooting and preventive and predictive maintenance. Some of these include:

Increased safety

Technicians can inspect areas and equipment from a safe distance. They don’t need to interrupt operations, nor have to climb ladders or use a lift to scan ductwork and high ceilings.

Improved reliability

Reduce unscheduled downtime by attaining more accurate information for easier maintenance and repairs. Easily identify and address the problem before it results in large-scale losses.

Better assurance of repairs

An infrared camera allows technicians to quickly scan repaired components or structural areas to very that a repair was successful, or identify if further repairs are needed.

Successful commissioning of new installations

Infrared thermography can be used to document the condition of new equipment at the time of acceptance. The baseline documentation can be used to verify the manufacturer’s performance specifications or provide a basis for comparison at another time.

Improved production rate and quality

Preventive or predictive maintenance can minimize equipment malfunctions and failures.

Monitor equipment deterioration

Maintain optimum production efficiency by monitoring the condition and characteristics of your equipment with a thermal imager, against predetermined tolerances. This will allow you to repair or replace deteriorating components before they fail completely and potentially cause unplanned downtime.

Invest in a quality thermal imager from Fluke and reap the benefits.
