Detection of fault occurrences within a power distribution system. A transient detector and fault classification system () implements an algorithm that detects transients which may result from the occurrence of a fault in the power distribution system. The system includes a detection module () which processes a set samples obtained from electrical waveforms propagated of through the power distribution system and appear to be statistically anomalous compared to other sample data. This is done using an adaptive detection algorithm that is applied when large changes occur in a waveform over a relatively short period of time. The identified samples are then provided to a signal classifier module () which processes sets of samples to classify a transient they represent as a likely fault occurrence or some other type of anomaly which is likely not a fault occurrence. If a transient is classified as representing a likely fault occurrence, a polling module () polls users of the distribution system to determine if a fault has occurred within the distribution system, and, if so, where.
