Title:
GROUND DETECTOR FOR AC GENERATOR
Document Type and Number:
Japanese Patent JPS5826524
Kind Code:
A
Abstract:
The present invention relates to a ground detection arrangement for an A.C. generator in which positive and negative D.C. voltages are alternately applied to the neutral point of an armature winding so as to detect voltages proportional to ground currents corresponding to the respective D.C. voltages, and the average of the sum of the absolute values of both the detected voltages is compared with a reference value thereby to detect the existence of grounding, whereby the existence of the grounding can be detected without being affected by the grounding position of a field winding.
