Electrical thermographs

The thermographic technique is commonly used to monitor electrical installations in all its applications. For example, inMV-AT and MV-MV generation and distribution plants and MV-MV and MV-BV end-user plants

In electrical systems, heat is an important factor, normally generated by contact resistance and circulating current intensity, a phenomenon known as the Joule effect. As either quantity changes, there will be an increase in temperature such that overheating of the components will be generated, causing structural failure.

Minimum conditions for undertaking a proper thermographic survey

01

Divide the equipment to be monitored into primary and secondary, giving objectivity to critical equipment;

02

Equipment must have reached its thermal regime for at least one  day

03

The minimum recommended load is 40% for MV-LV breakers and 30% for HV breakers

03

There must be no coverings (plastic, glass, sheet metal) between the operator and the equipment being inspected.
