What is repeated grounding - Solutions - Huaqiang Electronic Network
Ground one or more points on the zero line again, and repeat the grounding. In order to ensure safety, the neutral line is also grounded repeatedly several times, that is, several points at different points of the zero line are grounded to the ground. The purpose is to prevent the grounding protection from failing when the neutral line is broken. It can also reduce the ground voltage of the neutral line and reduce accidents. If only one neutral line is grounded, once the neutral line is broken, the protection zero is lost. The voltage on the casing can be as high as the phase voltage, which is very dangerous.
