Property managers are always liable for the electrical safety of the properties under their management. Insurance companies may
evaluate and consider lowering their premium if managers can submit evidence that the electrical system is under a meticulous maintenance
program. One of the many revealing maintenance programs is to carry out an Infrared Thermography Surveillance for the electrical
switches and panels.
What Is Infrared Thermography?
Infrared thermography is also known as thermal imaging. It is a diagnostic tool used for predictive
maintenance. Infrared imaging systems are used to scan equipment and structures, and to produce "heat" pictures from which temperature
measurements can be made.
What Is Infrared Thermography Used For?
Thermographic studies, as part of electrical inspections,
are used to identify electrical problems due to loose or bad connections that cause arcing and high temperature. This increased temperature
can then cause components to fail, potentially resulting in unplanned outages and injuries.
In addition, the efficiency of an electrical
grid becomes low prior to failure. Thus, energy is spent generating heat, causing unnecessary losses. If left unchecked, heat can
rise to a point that connections melt, breaking down the insulation and breaking the circuit. As a result, fires may occur.
At AA Electric, we use FLIR Systems' ThermaCAM® systems for thermal imaging. ThermaCAM systems detect
as small as 0.07°C in objects, which is ideal since the typical
industrial electrical or mechanical problems occur when there is
increase of 10°C or more. The ThermaCAM systems are sealed and hardened
for use in extreme and potentially hazardous
technology does not require power outage in the electrical system, so it does not create any inconvenience
