Abstract
Fault analysis and detection involving a generator neutral ground includes monitoring a voltage waveform across a neutral grounding transformer of a generator. During monitoring of the voltage waveform a sample of the voltage waveform is acquired. Previously, a number of similar past samples of the monitored waveform were acquired and stored as well. The present sample is compared to one or more of these stored, past samples so that, based on a similarity between the present sample to the past samples, a generator fault indicated by the present sample can be identified. Identifying the generator fault can include recognizing that it is presently occurring or that it may occur in a predictable timeframe. Additionally, identifying a component of the generator that caused, or will cause, the generator fault can be identified as well. A diagnostic message or control signal based on the identified generator fault can then be generated.
