Description: Three-phase transformer grounding transformer (or three-phase reactor), used to point ungrounded power system to provide an artificial neutral point can take the load for the power system grounding, which can be connected to the neutral point of the arc s

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.
