Why You Must Make Electrical Infrared Inspection Part Of Your Maintenance Program

By Lisa Williamson


In electrical systems, high temperatures normally indicate an impending trouble. This can result from unnecessarily high resistance, short circuits, poor connections, ground fault or any other failing components common with electrical equipment. The problem must be pinpointed and rectified early enough as complete failures are normally expensive and at times can results to catastrophes. Instead of struggling to find the incipient failures through visual and other manual inspection methods which are costly, time consuming and may not pinpoint the problem, engineers are now turning to electrical infrared inspection that has proved to be the most effective alternative.

The general recommendation is that all parts of electrical system that are exposed to vibrations and or any other movements are inspected at least every six months while the rest are inspected on annual basis. For the system exposed to earthquakes, frozen winter conditions, very strong winds and tsunamis, there is a need for more frequent testing.

In normal distribution, infrared surveys should be conducted on annual basis and is considered part of a regular preventive and maintenance program. This form of testing makes it possible to inspect a large number of components within the shortest time possible locating the faulty items in the system that could not be located through the physical survey or testing.

The other benefit of this survey is that there is no need to shut down the system. It is a non-contact a nondestructive form of testing (NDT) that allows for work continuation without interrupting system production. The equipment get inspected under normal loads and the normal operating condition by scanning devices to reveal the existing and emerging problems before it is too late.

Using the state of the art equipment deployed for scanning, thousands of components get inspected in a matter of hours with very accurate results. With very high rate of efficiency and effectiveness, most of engineers are now using this form of inspection. It cut down on staff needed for the job and increases profitability by a big margin. In fact, it has one to four returns on investment and as such, companies that hope to survive into the future have to adopt this technology.

Given that thousands of devices can be tested within hours, it has proven to be more convenient, highly effective and very efficient method of maintaining electrical system replacing the physical inspection. It is also endorsed by the National Fire Protection Association and the InterNational Electrical Testing Association among other bodies that now advocates for its use.

This form of testing and survey therefore saves engineers millions of dollars improving profitability and significantly decrease the expenses in the areas of operations, testing and maintenance in general. With this convenience and financial benefits, this is a technology you cannot afford to miss in this century if you think of remaining in business.

It is important to trust the surveying services to a company that has expert engineers, the necessary machinery for the job and well proven track record in order to enjoy the full benefits of this new technology.
