Surge Arrestor testing

Surge arrestor testing is a critical practice in safeguarding electrical and electronic systems from voltage spikes and surges. Surge arrestors, also known as surge protectors or lightning arrestors, play a pivotal role in protecting equipment and systems from transient overvoltages that can cause damage and downtime. Effective surge arrestor testing ensures that these devices remain fully operational and capable of diverting harmful surges away from sensitive equipment. Surge arrestor testing involves several key procedures. One of the primary tests is the measurement of clamping voltage, which verifies the surge arrestor’s ability to limit voltage levels during a surge event. Additionally, insulation resistance testing is performed to assess the insulation quality and integrity of the device. Leakage current measurements and discharging tests are also carried out to ensure proper functionality.
