Secondary circuit wiring checking system

The utility model belongs to an operation inspection device of a power transmission and distribution circuit and relates to a secondary loop wiring inspection system for inspecting and determining the wiring condition of a secondary loop of a power transmission and distribution system. The inspection system comprises a current mutual inductor for inducing current in a primary loop, wherein the extraction wire of the current mutual inductor is connected with a meter of the secondary loop; the system further includes an annular winding frame; a segment of detection wire is wound on the outer circumference of the annular frame by at least two rounds; and the detection wire is connected between the extraction wire of the current mutual inductor and the meter through the both ends thereof. The secondary loop wiring inspection system can inspect and determine the wiring condition of the secondary loop of the power transmission and distribution system in an idle state.
