A device that supplies or consumes reactive power comprised solely of static equipment. It is shunt-connected on transmission lines to provide reactive power compensation.

An electrical relay in which the designed response is developed by electronic, magnetic, optical or other components without mechanical motion. Excludes relays using digital technology.

A particular type of Static Var Compensator, in which Power Electronic Devices such as GTO’s are used to generate the reactive power required, rather than capacitors and inductors.

A cell containing little or no free fluid electrolyte solution. This enables gasses to reach electrode surfaces readily, and permits relative high rates of recombination.

A unit relay which responds to abnormal conditions and initiates the operation of other elements of the protection system.
