摘要
The proposed device for measuring voltage drop in the secondary winding circuit of a voltage transformer contains two isolating transformers, a measuring and computing unit, and a display. The terminals of the primary windings of the isolating transformers are connected to the terminals of the secondary winding circuit of the voltage transformer via a twisted-pair cable. The secondary windings of the isolating transformers are connected inversely in series. The inputs of the measuring and computing unit are connected to the corresponding terminals of the secondary windings. and via an additional isolating transformer, to the corresponding terminals of the primary windings of the isolating transformers. The output of the measuring and computing unit is connected to the input of the display.
