for street lights you may to understand somewhat, to its common grounding system for street lamp you understand? Don't understand or want to further understand friends with small make up into the following article to learn about it: street lamp grounding is generally transformer, and then set up ground in the past, each lamp pole grounding line, or is the base of the lamp pole when the buried depth is one of the steel with a local line. Earthing transformer its role, simple say, made a neutral earthing transformer is artificial, used to connect the grounding resistance. When the system ground fault occurs, the positive sequence, negative sequence current in high impedance LED street lamp, low impedance to ground for the zero sequence current protection and reliable action. Then through an arc suppression coil grounding, together with the arc suppression coil earthing protection of the power system. Prevent system when the single-phase grounding fault location of intermittent arc over-voltage on system and expand the accident. Stand for substation with variable refers to the low voltage power and lighting step-down transformers. Standing with change sometimes grounding can also be used to balance.
