In general a surge is a transient wave of current, voltage or power in an electric circuit. In power systems in particular â and this is likely the most common context that we relate surges to â a surge, or transient, is a subcycle overvoltage with a duration of less than a half-cycle of the normal voltage waveform.urges are generally measured in microseconds. Every piece of electrical equipment is designed to operate at a specified nominal voltage such as 120 Vac, 240 Vac, 480 Vac, and so on.
What is surge protector? Surge protector also known as Transient Voltage Surge Suppressor (TVSS), Surge Protection Devices (SPD) or Surge Suppression Equipment (SSE) is the equipment designed to protect electrical and electronic equipments from power surges and voltage spikes.
