Abstract
A system of tracking load switching operations and fault clearing operations of at least one circuit breaker in a power circuit includes at least one coil antenna sensing changes in a magnetic field around the coil antenna. The changes in the magnetic field induce corresponding changes to a current or voltage in the at least one coil antenna. A receiver is connected to the at least one coil antenna and receives the current or voltage. A computer is connected to the receiver and stores a data stream that corresponds to the changes in magnetic field around the at least one coil antenna. The computer uses the data stream to generate a plurality of characteristic magnetic field waveforms for the at least one circuit breaker. The computer assembles a low frequency magnetic signature for a respective circuit breaker from the characteristic magnetic field waveforms generated for the respective circuit breaker.
