ABSTRACT:
In apparatus for indirectly measuring the output DC current of a rectifier device on the input side of a polyphase rectifier transformer, a polyphase auxiliary current transformer is provided and the polyphase primary or secondary windings thereof are combined such that the area of the decreasing secondary current waveform is made equal to the area of the increasing secondary current waveform during commutation thereby releaving the secondary current from the adverse effect of the overlap angle.
