Вдосконалення захисту від однофазних замикань на землю обмотки статора синхронного генератора

Abstract

The method of realization of functional description of protection of stator winding of synchronous generator from monophase earth-faults,is suggested, based on the calculation of current of loss on earth, on the basis of measuring of pure resistance the isolation of stator winding in relation to earth and resistance in the place of shorting in first moment of its appearance, and also parameters of stator winding of synchronous generator, which are considered permanent.
