A “corona camera” used for detecting corona discharge in high-voltage transmission lines is an instrument designed to identify and visualize the corona effect. Corona discharge is an electrical discharge that occurs when the electric field near a conductor exceeds the dielectric strength of the surrounding air, leading to a faint glow or a series of small electrical discharges. Detecting corona discharge is important in high-voltage power systems, as it can lead to power losses, equipment damage, and even safety hazards.
Corona cameras, also known as ultraviolet (UV) or ultraviolet-visible (UV-Vis) cameras, are equipped with sensors that can detect ultraviolet and sometimes visible light emissions associated with corona discharge. These cameras make it possible to identify and locate corona issues in electrical transmission and distribution systems. By pinpointing areas with corona discharge, maintenance and repair teams can take corrective measures to reduce energy losses and prevent potential equipment damage.
