- Published : 2009.10.09
Abstract
Recently, load circuits and components of customer are various. Therefore failures of ELB(Earth Leakage Breaker) and MCCB(Molded case circuit breakers) are more frequent. Lite time of MCCB even if there is same units differ from environment, condition of operation. FEMCA is a efficiency method of system operation or maintenance for system reliability. We study on FMECA procedures and method. In this paper, we focused on FMECA application to MCCB life time test.
