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

By Lisa Williamson


Proper management of an electrical system is a basic requirement considering just how a small mistake can turn out to be the cause of a disaster. Malfunctions can be caused by human errors during installation, vandalism or damages from physical elements. The only way out is periodic inspection with the aim or reveling flaws, points of weaknesses and other potential disasters well in advance for early repair. This process does not have to be time consuming and labor intensive as is normally the case when physical testing is done, instead it is prudent to resort to electrical infrared inspection that is highly effective and a significantly cheaper alternative.

Through this method of inspection, it is much easier to locate the underlying problem reducing downtime and equipment damage. It also come with additional benefits such as prevention of catastrophic failures well in advance, help establish repair priorities, improves preventive and maintenance efficiency and provides for testing under load hence avoiding costly shutdowns.

The target is to pinpoint any damages or potential threats resulting from improper installations, points of weaknesses, contamination, corrosion or worn out devices. The other problems can result from ground faults and improper assembly leading to increased resistance which is the recipe for overheating which on its own is a danger to the rest of the system and the surrounding objects. If left unchecked power outages are the least of problems that can result.

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.

This is the best way in terms of cost and time to inspect almost all electrical components. The most common components that need regular inspection include transformers, switchgear, bus ducts, power correcting banks, variable frequency drives, the disconnects, distribution centers and panels, sub-feed panels, the motor control centers, the uninterruptable power supplies, the lighting and the receptacle panels among several other components.

This form of inspection is endorsed and recommended by several associations and regulatory bodies such as the InterNational Electrical Testing Association and National Fire Protection Association among several others. It has 1 to 4 returns on investment for both the labor and material used. It is this cost benefit analysis that make is a viable business for many companies that now offer this service.

There are several benefits that comes with infrared surveys among which include the ability to pinpoint the real hot spot, the reduced down time, elimination of unplanned power outages, ability to cut down on the cost of maintaining electrical system and minimization of possible hazards and related disasters. This all translates to an efficient and reliable electrical system with reduced cost of power supply.

Part of the decision to use this cutting edge infrared detection technology requires that the companies you choose for your inspection job are certified. They should have experienced engineers for the job with a proven work record. With the correct inspectors, you will be able to significantly reduce unscheduled power outages and increase energy efficiency, safety and dependability in general.
