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.
