WebAug 22, 2024 · 1. Single Rotor Earth fault. The field winding of a synchronous machine is usually floating with respect to ground. This means it is not grounded at all. So a single earth fault does not draw any fault current as there is no closed path to flow. The Single earth fault currents which are negligible amounts are limited by Neutral impedance.
