What is Zig-Zag Transformer Grounding Guide about?
The document discusses sizing an earthing transformer given system parameters. It recommends: 1) Rating the earthing transformer to withstand ground fault current longer than the neutral earthing resistor, such as 1 minute, to account for the transformer heating under fault conditions. 2) Calculating the estimated ground fault current based on system voltage and impedance, then using this to size the zigzag transformer winding to carry 1/3 of the fault current. 3) Considering fault current magnitude an
