Thermography

Thermography is a science of using electronic optical devices to detect and measure radiation and correlating that to surface temperature. Abnormal heating associated with high resistance or excessive current flow is the main cause of many problems in electrical systems.

Infrared thermography allows us to see these invisible thermal signatures of impending damage before the damage occurs. When current flows through an electric circuit, part of the electrical energy is converted into heat energy. This is normal. But, if there is an abnormally high resistance in the circuit or abnormally high current flow, abnormally high heat is generated which is wasteful, potentially damaging and not normal.

Thermography is the latest analysis tool for the detailed energy audit as the thermal cameras are powerful tool in viewing wall cavity insulation, ceiling insulation, moisture related problems. Several areas in electrical installations are not easily identified using conventional methods but these are able to locate with Thermal Imaging. Infrared Thermography is one solution for diagnosis used to determine the most effective plan of action to make the electrical installation more energy efficient.

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
