Attending To Power Harmonics With Fluke Tools

Newton’s third law says that for every action, there is an equal and opposite reaction. We are reaping the consequences of the actions of the generation before us. Harmonics has been around for a considerable amount since the introduction of electronic drives for motors, fans, and pumps. Let’s learn more about harmonics and how to address this problem.

What is Harmonics?

Harmonics are the side effects of electronics. These are distortions in the normal electrical current waveform transmitted by non-linear loads. When harmonics are combined with fundamental frequency, this creates distortion in the waveform which causes an adverse effect on your electrical equipment and power lines. Harmonics can be detected by checking these:

1. Load Inventory

2. Transformer Heat Check

3. Transformer secondary current

4. Sub-panel neutral current check

5. Receptacle neutral-to-ground voltage check

Switch-mode power can be seen on electrical devices such as photocopiers, personal computers, laser printers, fax machines, and battery chargers. They are commonly used in supply design because of their ability to supply a fixed voltage output continuously.

Dangers of Power Harmonics

Dealing with electricity can be hard at times because of the dangers it carries with it. There are power systems that can handle a certain level of harmonic currents. But if there is a significant load more than the power system can hold, it can cause errors in communication, overheating, and hardware damage. Here is some hardware damage that can happen:

  • Overheating of electrical distribution equipment, cable, transformers, standby generators, etc.
  • Metering errors
  • Generator failures
  • False tripping of branch circuit breakers
  • Lower system power factor resulting in penalties on monthly utility bills
  • Crest factors and related problems
  • Fires in wiring and distribution systems
  • High voltages and circulating currents caused by harmonic resonance

But these circumstances can be avoided with proper maintenance using dependable maintenance tools.

How To Prevent Overheating Electrical Panels Using Fluke Tools!

Let’s give a brief background on why electrical panels are important to every household, or to every establishment in general. This little rectangular box holds the power to every electrical aspect of buildings and houses. We know it can seem a bit intimidating to look at but once you get the hang of it, it’s straightforward. Let’s just say that without electrical panels, you won’t be able to have control over electricity in certain areas of your home (if you’re a homeowner) or establishment (if you’re a maintenance professional).

Whether it be on buildings, homes, industrial plants, or in any area that requires electrical power, they will never be alive without electrical panels. So, regarding their importance, what would now happen if you had a faulty electrical panel in your midst, or worse, an overheating one? Here’s how you can resolve them with early detection using Fluke tools!

Reasons for overheating electrical panels

Initial, don’t be confused. All electrical panels may feel a bit warm since electrical currents run through them. There is a difference between a warm electrical panel and an overheating one. Remember, each circuit breaker is assigned to one current flow. Take a house, for example, one current flow (that is aligned to a breaker) may be connected to the bedroom, another can be connected to the kitchen, and so on.

Take note that circuit breakers also have ratings. So, if it exceeds that rating, it will also be a cause of a warm-up. However, these are not the only reasons why your panels are heating up. Here are some more probable reasons why they are overheating…

It might be a case of a loose connection.

Watch out for loose connections as this can generate heat. Loose connections often happen with the breakers. You see, when installing these little switches inside the electrical panel, you need to make sure that it is secured with the clip that holds them to the bus bar. If all else fails, maybe you need to bring out your screwdriver and tighten the lug that holds the breaker.

Current limits may also be in the works.

Keep in mind that electrical panels consist of multiple currents in different breakers, therefore, when one of those currents exceeds their rating then there might be a “trip” to the current flow breaking electricity. This can be a cause of power-hungry appliances. And, more often than not, when such appliances are often turned on and off, this can cause distress on your breaker. A simple solution would be to reset it. Switch it off, and switch it back on.

Faulty breakers also make electrical panels to overheat.

How do you know if one of your breakers is bad? An indication can be flickering lights or if your power is not working continuously in certain areas of your place. These are some of the signs that you have a bad breaker on your hands. If in such circumstances you’ve had your breakers replaced and are still experiencing the same thing, then it might be high time to upgrade to a modern panel.
