Abstract:
1. A method for monitoring electrical faults in a power plant electrical distribution system, comprising: monitoring and sampling in real time with an EDS electrical fault monitor (EFM) operation state (OS) radio frequency (RF) emissions data from electrical distribution system (EDS) equipment that are obtained with a plurality of time synchronized radio frequency monitors (RFM) that are distributed about the EDS and coupled to the EFM, the OS RF emissions potentially indicative of electrical faults in the EDS; storing in an automated data storage device that is coupled to the EFM OS data samples for each RFM, sampled data including the RFM identification, data sample time and data sample waveform characteristics; determining with the EFM in real time a likelihood of whether one or a combination of the respective OS data samples is indicative of an electrical fault by: causing the EFM to generate an alarm when any of the sequentially determined first through overall SO confidence levels is indicative of an electrical fault within the EDS.
