Shunt trip disconnecter - provides maximum protection by interrupting all power to the system in the event of a control sensed malfunction or overcurrent.
Because of the current on the shunt reactor, traditional traveling wave differential protection cannot be applied to transmission line with shunt reactor.
由于并联电抗器两侧的电流发生变化，传统的行波差动保护无法应用于带并联电抗器的输电线路。

Therefore, it is of great necessity and significance to develop more advanced protection device for UHV line shunt reactor.
