Model for Quantifying the Effect of Circuit Breaker Maintenance Using Condition-Based Data

Recent trend in maintenance is to optimize the frequency of inspection and repair according to the condition of the equipment being maintained. Condition-based maintenance introduces additional investment in monitoring equipment and analyzing systems. This approach is acceptable only if the benefits are greater than the existing cost of maintenance and additional equipment/software. Low cost "circuit breaker monitors" along with signal processing modules and expert system modules are available to monitor the circuit breaker control circuit signals. This paper presents a model for quantifying the effect of circuit breaker maintenance using the on-line condition data. This model can be used in developing system level maintenance strategies.
