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

Test your batteries regularly with highly functional and reliable tools like Fluke 500 Series Battery Analyzers available at www.presidium.ph.

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.

2. 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.

3. 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.

4. 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.

5. 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.

As it offers plenty of benefits for every mechanical personnel or engineer, there is no doubt that the Fluke 62 MAX+ infrared thermometer has been the top choice in troubleshooting HVAC mechanical systems. It surely is an efficient diagnostic tool that can save any mechanical personnel’s money out of the box! A device that works literally with just a “point and shoot” technology, one might consider Fluke 62 as an indispensable tool providing several helpful ways for any measurement and calibrating operations as discussed below:

1. Provides accurate temperature measurements

One of the most noticeable features of Fluke 62 MAX+ is its ability to accurately control any temperatures. It is the preferred choice when checking any discharge air temperature. It can also accurately check room thermostat quickly. As well as water coils in HVAC systems can be monitored if it is running the right temperature measurements with the use of the Fluke 62 MAX+. It indicates proper water temperatures and sees if there are any water balance problems. The reliability of the Fluke 62 MAX+ in providing accurate measurements of temperature reduces energy waste and increases comfort in daily mechanical operations.

2. Helps check equipment operations

A well-maintained HVAC system requires a lot of energy used in testing operations. One of the things that determine a functional HVAC is its steam traps. A failure can result to improper system operations as well as a system freeze up; that is why the Fluke 62 MAX+ is the perfect tool in identifying if a steam trap is broken or needs fixing. Control panels are also crucial elements for every HVAC system. The Fluke 62 MAX+ IR Thermometer enables mechanical personnel to spot the power supply failure and what is causing the improper operation. HVAC’s humidifier can also benefit from the Fluke 62 MAX+ as it helps determine water or steam presence thus increasing the safety of the operator when inspecting the humidifier.

3. Always provide equal distribution of required elements

Aside from helping determine accurate temperature measurements and ensure the functionality of the HVAC system, the Fluke 62 MAX+ IR Thermometer requires that a room or space has a function air distribution duct as it helps personnel identify which discharge ducts are shut off while noting those that do not show the correct discharge temperature. This device can also help commercial buildings in maintaining their cooling system by making sure that the chilled water temperature matches the set point.

Fluke 62 MAX+ IR Thermometer has been one of the best, if not, the top choice for every mechanical and HVAC calibration operation. It has been tried and tested by many. It surely is the conventional device that you have been looking for! Presidium.PH Corporation is the country’s top distributor of Fluke instruments.

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.)
