Price Surge Arrester is a protective device specifically for electrical systems against over voltage without having to disconnect the network. Surge arrester is a device that can be used to protect electronic equipment from lightning induction. Lightning induction can cause damage to electronic equipment such as computers, PBX, telephone, CCTV and DVR, etc.
Surge Arrester function to neutralize lightning currents entering through the protected path. If there is a current that exceeds the maximum capacity (Imax), then the arrester will block then decide with an electronic circuit inside it. The over voltage is discharged to grounding. So it needs a good grounding system so that arresters can function optimally.
