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.

It is a good practice to inspect all electrical system components twice a year or at least every 12 months at minimum. When properly conducted, it is possible to detect and prevent accidents well in advance before they occur. For the equipment and the control systems that are subjected to movements and vibrations, every six months inspection is not optional.

Excessive heat is normally an indication of the underlying problem that must be handled before a disaster. Other than mechanical damages to power lines and other electrical devices, there are several causes of overheating but the common ones include faulty assembly, loose connections, wear and tear, ground faults, contamination and corrosion. Most of these results from exposure to physical elements and thus calls for periodic inspection.

The devices that requires infrared surveys are the bus ducts, the distribution center, the distribution panels, receptacle panel, the transformers, lighting system, switchgears, disconnects and other components that make up the system. If well done, the uninterruptable power supply can be achieved as there is no need to shut down the system. The process of inspection takes place under the normal load without any disturbance to normal supply.

If you choose to use this form of testing, there is no need to shut down any part of the system as the testing is non-contact and nondestructive (NDT) at the same time. This means that all components can be inspected under their normal loads in the normal operating system. It involves scanning with the aim of revealing improper connections, damages and any form of flaws well in advance before they can result to any disaster.

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.

In order to fully benefit from this cutting edge technology, you must be very keen on the companies you choose for the job. At minimum, the prospective company must have some proven record of good job done on previous assignments. For a good choice, the level of experience of staff also matters.
