    System working principle: The sensor of the detector is a residual current transformer. Under normal conditions of the line and electrical equipment, the vector sum of the currents of the phases A, B, C, and N is theoretically zero. The secondary winding of the residual current transformer has no Voltage signal output. When the insulation drop or ground fault occurs, the vector sum of the phase currents is not zero. The fault current causes a magnetic flux in the toroidal core of the residual current transformer. The secondary winding senses the voltage and outputs a voltage signal to measure the residual. Current. Considering the unbalanced current of the electrical circuit and the normal leakage current of the line and electrical equipment, the actual electrical circuit has a normal residual current. The alarm is only issued when the residual current reaches the alarm value. The temperature detector is industrial-grade thermal ...... see details
