An alternating current system residual current monitoring device operation verification device and method

Abstract

The application discloses an alternating current system residual current monitoring device operation verification device and method, and belongs to the technical field of residual current monitoring device verification. The verification device comprises a verification control unit, at least one verification unit and at least one verification CT. The verification control unit sends a control instruction to each verification unit according to the expected current of the residual current monitoring device to be verified, so as to control the output current of each verification unit. The current output port of each verification unit is short-circuited through the corresponding configured current output lead, so that the current output lead flows through the output current of the verification unit. Meanwhile, the current output lead bypasses the current monitoring CT corresponding to the verification unit, so that the current monitoring CT can simultaneously measure the real-time disturbance current and the output current of the line. Each verification unit measures the real-time disturbance current of the line through the corresponding configured verification CT. The application can be used for residual current monitoring device operation field verification, test acceptance and the like.
