2. Basic principles
Short circuit principle: When the circuit has a short circuit fault, the short circuit sensor senses the fault current, and at the same time converts this signal into a data signal and sends it to the host, then the two-phase short circuit fault indicator on the host panel is on, showing the line where the fault occurred.
Grounding principle: The grounding part is based on the detection of the zero-sequence current of the line. When a ground fault occurs in the system, if the grounding indicator on the panel is on, it indicates that the cable system has a grounding fault.
