Background
The small current grounding system is a three-phase system with a neutral point not grounded or grounded through an arc suppression coil and high impedance, and is also called a neutral point indirect grounding system. When a ground fault occurs in a phase, the ground fault current tends to be much smaller than the load current because a short circuit cannot be formed, so this system is called a "low current grounding system". When the fault occurs, because the current at the fault point is very small, the line voltage between three phases still keeps symmetrical and has no influence on the power supply of load equipment, the equipment in the system is allowed to run for a short time, and the equipment can run for 1-2 hours generally without tripping, so that the reliability of the power supply is improved. However, grounding of one phase causes the voltage to ground of the other two phases to rise by several times the phase voltage, which threatens the insulation of the equipment, and if the grounding is not timely processed, insulation damage, two-phase short circuit and arc discharge can develop to cause overvoltage of the system.
