ABSTRACT

Circuit breakers are of inevitable use in this modern era of electronic and electrical boom. In this paper, the problem of “Nuisance tripping” caused due to environmental impact forces in circuit breakers is analyzed. Formerly, impact response of a circuit breaker latching system was analyzed only using through practical experimentation which proves to be very costly, given the cost of sophisticated equipment used for the testing and the associated employees’ over head costs along with other indirect costs. In this research paper, a theoretical model was developed to determine the impact response of a circuit breaker system under the application of prescribed impact forces. This model can be used by a design engineer to predict the impact response of the designed circuit breaker latching setup. So, even before the manufacturing of trial runs begins, an engineer can be very sure that his component designed will withstand the standard impact forces. Hence, the above said costs incurred due to impact testing and the associated reworking costs can be neglected, or at least minimized to a considerable level. This research mainly focuses only on the methodology to be used with circuit breakers to predict and analyze the impact responses.
