Abstract

Abstract: The rotor winding earth fault is not occurred commonly if the generator maintenance is perfect, but there are something could cause the fault which includes the ageing of generator, the absent of scientific and effective maintenance and defects left over in manufacture etc. Grasp of scientific, rational detection method is helpful to eliminate the fault fast and easily.

Key words: rotor winding earth fault, consequence of earth fault, reason of earth fault, measure
