Zigzag grounding transformer

The grounding transformer is a transformer intended solely for establishing a neutral connection point on an ungrounded power system, then grounded with the arc suppression coil or the low resistance

To specify a zigzag transformer, the follwing information should be considered



1.Provide the line to line votlage of the system

2.Provide the magnitude of the neutral current

3.Provide how long the neutral current will flow

4.Provide the system impedance per phase
