insulation monitoring : for places that need to ensure the continuity and safety of power supply, an insulation monitor is installed to monitor the insulation status of the system to the ground in real time. When the insulation resistance decreases, the system generates an audible and visual alarm, prompting personnel to rectify the fault .
short circuit protection : cut off the fault circuit before the short circuit current produces a huge thermal effect and the electric force causes harm to the conductors and connectors. Usually, the switching equipment is required to have a short delay or instantaneous trip .

Overload protection : When an overload fault occurs, the overload current should be cut off before the conductor temperature rise caused by the overload current damages the conductor insulation, connectors, terminals and surrounding substances, but greater losses should be avoided if the circuit is suddenly cut off.
