Patent ID: 10310017

Abstract:
Aspects of the invention provide a system and method for detecting inter-circuit faults within a generator stator. In one embodiment, a computer system includes: a sampler for sampling phase voltages and phase currents of a generator stator; a plurality of pre-defined blocks for enabling, based on the sampled phase voltages and currents, an inter-circuit fault detection scheme; a level detection block for determining, in response to the enabled inter-circuit fault detection scheme, a plurality of differences between the sampled phase voltages; and a comparison logic device for comparing, in response to the enabled inter-circuit fault detection scheme, each of the differences of the sampled phase voltages and determining, based on the differences, an inter-circuit fault within at least one phase of the generator stator. The system may also include a negative sequence voltage block for detection of inter-circuit fault within a generator stator.
