Abstract: A method and apparatus provide an improved way to monitor a circuit for deterioration and obtain an advance warning of the deterioration so that action can be taken before the circuit breaker may trip for the circuit. The method establishes a baseline for the circuit, including monitoring the zero crossing point for the voltage and current for the circuit. In operation, the circuit is monitored using the zero crossing point and this information is compared to the baseline to determine if a change has occurred. The baseline information establishes thresholds that signify that the circuit is deteriorating so that the appropriate signal can be provided so that an appropriate action can be taken, interrupt the circuit, take remedial action, etc.

Abstract: A method of monitoring the condition of a circuit comprises establishing a known baseline signal for a type of circuit (each is somewhat different) and defining these characteristics in terms of the lead and trailing edge angular components (@ zero crossing point), the voltage (amplitude), and the period (time length) of the waveform. Ideally, the angular component of the square wave should be vertical, or at 90 degrees to x-axis. The baseline non-regular square wave that is composed of current, voltage, any harmonic thereof, or the combination of these signals which best indicate predictive measurement attributed to the type of circuit being monitored. Future wave forms indicate the rate of decay based upon the aggregated angular, amplitude, and period components of the zero-crossing points when compared to the baseline signal and/or prior waveform of the observed specific splice. The rate of decay can help determine the life expectancy of the circuit.
