Claims

[Scope of utility model registration request]

A device for testing the secondary circuit side of an instrument phase transformer installed in the main circuit of a power distribution board, which selectively applies a rectangular wave pulse to a predetermined phase or between phases of the main circuit of the power distribution board based on a phase switching signal. a main circuit pulse generator that supplies a phase changeover signal, a phase changeover switch that generates the phase changeover signal, and a pulse generator that receives pulses from a secondary circuit of the instrumentation transformer and determines the polarity of the instrumentation transformer based on the received signal. 1. A testing device for an instrument transformer, comprising: and a transformer secondary pulse receiving/determining device comprising means for determining a phase.
