Abstract

A method of monitoring electrical faults includes processing features of signals output by sensors of a circuit breaker about electrical properties of a circuit coupled with a load and transitioning between states of operation based on the processed features. The states include a normal state, a fault state, and a trip state, wherein the state remains in the normal state until the processed features no longer satisfy normal criteria, after which the state transitions to the fault state, wherein the state transitions back to the normal state when a trip condition is not satisfied, and transitions from the fault state to the trip state when the trip condition is satisfied. The method further includes detecting a warning event when the state transitions from the normal state to the fault state and back to the normal state and outputting a warning event notification upon detection of the warning event.
