What Does an Electrical Thermal Imaging Survey Entail?

A thermographic survey has to do with collecting thermal images of electrical components including contactors, switchboards, motors, UPSs, control panels, fuse boards, transformers, battery banks, etc. With this survey, it becomes easy to detect electrical faults such as overloaded circuits, transformer cooling malfunction, induced current, loose connections and motor winding faults. These operations are done while the appliance is working, causing zero disruption to commercial activities.

After the survey, a report is produced, showing the faulty equipment. For every fault detected, diagnosis, as well as recommendations for repair, is given. The report will also give an evaluation of the severity of the fault which will enable the clients to make an adequate plan on the next line of action to take in order to remedy the situation without affecting their business activities.
