A component monitoring system structured to monitor circuit breaker assembly component characteristics is provided. The component monitoring system includes a record assembly, a number of vibration sensor assemblies, a comparison assembly, and an output assembly. The record assembly includes selected nominal data for a selected circuit breaker component. The vibration sensor assembly is structured to measure a number of actual component characteristics for a substantial portion of the circuit breaker assembly and to transmit actual component characteristic output data. The comparison assembly is structured to receive an electronic signal from said record assembly and said sensor assemblies, to compare each sensor assembly actual component characteristic output data to said selected nominal data and to provide an indication signal as to whether said sensor assembly output data is acceptable when compared to the selected nominal data. The output assembly includes a communication assembly and an output device.

Resistance values for a first time for respective areas of a plurality of electrical connections are generated. Respective normalized resistance values are generated from the resistance values. Respective temperature rise values for a second time for respective ones of the areas of the electrical connections are generated. An average temperature value is generated from the temperature rise values. Respective normalized temperature rise values for the generated temperature rise values are generated based on the average temperature values. An abnormal condition of at least one of the connections is detected responsive to the normalized temperature rise values and the normalized resistance values.
