    en.wikipedia.org/wiki/Surge_protector

    Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...

    [2] [5] The "8/20 μs" generator is designed for surge arrester testing, and produces a high-current surge into a low-impedance load. [2] On the other hand, modern electronic devices can be high and low-impedance loads simultaneously due to non-linear devices, protection circuits, and arcing in a dielectric breakdown.

    Surge protector – Protects electrical devices from voltage spikes; Flyback diode – Voltage-spike stopping diode across an inductor - a device to channel inductive spikes back through the coil producing them; Voltage sag – Short-duration reduction in the voltage of an electric power distribution system

  5. Power system protection - Wikipedia

    en.wikipedia.org/wiki/Power_system_protection

    Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...
