Why use corona cameras?

Corona discharge is associated with local high electrical field that exceeds the air ability to withstand and remain a dielectric gap. Corona can hit any medium/high voltage apparatus: transformers, bushings, capacitors, insulators, switchgear, conductors, cables, motors, spacers, switch cabinets, and more.

Corona is triggered by sharp edges, physical defects, contamination, bad design, wrong installation, improper material etc. Corona acts as a signal of existing faults, and at the same time corona itself radiates UV, creates Ozone (O3) and acids, dissipates audio noise and interferes with radio signals.

Seeing corona is advantageous to maintenance teams; pinpointing its origin is of great value and can reduce substantially inspection costs.

Ofil’s corona cameras lead maintenance engineers to origin of electrical failures, and cut inspection durations and reduce redundant activities such as insulators washing. During commissioning corona cameras immediately detect design issues. Corona cameras assist to avoid shutdowns, their use does not involve over loading, nor destruction of the tested elements. Using corona cameras has, according to our customers, helped them extend elements’ lifetime and slowed down aging processes.
