Thermographic Surveys and Periodic Verifications


Thermalec is an electrical preventative maintenance company using the latest thermographic and electrical test equipment to identify and report on potential operational and life-safety hazards.

Thermalec's objective is to reduce operational down-time, prevent potential accidents and, in most cases, save on costly utility bills.

Main Switch Boards (MSB)

Thermal imagers enable us to see the heat signatures associated with high electrical resistance long before the circuit becomes hot enough to cause an outage or explosion.  Be aware of two basic thermal patterns associated with electrical failure: 1) a high resistance caused by poor surface contact and 2) an over loaded circuit or multi-phase imbalance problem.

Distribution Boards (DB)

Above shows a thermal image recorded of an MCB distribution board during an electrical thermal imaging survey within a main switch room.
As can be seen in the thermal image, there is a temperature rise toward the red/L1 supply cable termination which was due to poor electrical contact at the cable termination and within the fuse assembly.

Circuit Breakers (CB)

This 20 amp circuit breaker has a loose wire screw.  The loose connection has increased resistance causing it to get hot.  Our high resolution imager clearly shows the hottest area of the wire is by the screw terminal.
