Abstract
The invention discloses a high potential side resistive current measuring system comprising more than one far end optical communication acquisition module, a local merging unit and a PC; the far end optical communication acquisition module is used for receiving synchronization acquisition pulse signals from the local merging unit, synchronically collecting current simulation signals of a primary sensor high precision non-inductive resistor, converting the current simulation signal into an optical digit signal, and sending the digit signal to the local merging unit; the local merging unit gathers optical digit signals returned by each far end optical communication acquisition module, carries out photoelectric conversion, and uses a net wire to send the signal to the PC machine according to a UDP communication protocol; the PC machine processes and parses the data, and displays corresponding information. The system directly measures the resistive current from the high potential side, thus preventing hidden troubles, caused by reversal connection in bridge measurement, on human body safety.
