grounding transformer
Grounding transformer short changed, oil-filled and dry according to the media, change can be divided into the ground; according to the number of phases, the ground can be divided into three phase variable variable and single phase grounding changed.
Ground change is man-made to create a neutral point, used to connect the grounding resistor. When a ground fault occurs, the negative sequence current on the positive sequence showed high impedance, zero sequence current form low resistance grounding protection reliable action.
