Some devices may absorb the spike and release it as heat. Typically the surge device will trigger at a set voltage, around 3 to 4 times the mains voltage, and divert the current to earth. Lightning that hits a power line can give a spike of over 100,000 volts and can burn through wiring insulation and cause fires, but even modest spikes can destroy a wide variety of electronic devices, computers, battery chargers, modems and TVs etc, that happen to be plugged in at the time. A voltage spike is a transient event, typically lasting 1 to 30 microseconds, that may reach over 1,000 volts. Surge Protection Device SPD for installation in a low-voltage distribution board.Ī surge protector (or spike suppressor, surge suppressor, surge diverter, surge protection device ( SPD) or transient voltage surge suppressor ( TVSS) is an appliance or device intended to protect electrical devices from voltage spikes in alternating current (AC) circuits.
