Claims

[Scope of utility model registration request]

Two current transformers are inserted in the line leading to the variable capacity shunt reactor, and two
A pair of side legs around which each side leg winding having the same number of turns is connected to the next winding, and a central winding having the same number of turns as the side leg winding and connected to the load. An auxiliary current transformer consisting of a tripod iron core having a central leg around which a wire is wound is provided, and a switch is provided that can freely short-circuit a part of the one side leg winding, and the switch can be used as a shunt. A protection device for a shunt reactor that opens and closes in response to an increase or decrease in the capacity of the reactor, and uses the output current of the central winding as a one-phase phase current as an input current of a protection relay.
