Abstract

PURPOSE: To enable to perform rational preventive maintenance, by determining the presence of failure, through the precise analytical inspection, by comparing every element of the circuit breakers with the performance of initial manufacture.
CONSTITUTION: The unit to detect the characteristics is given to each element of the circuit breakers to obtain the characteristic curves representing the operating condition of each element when the relay contact 1 is closed. The initial value of each characteristics curve is stored in advance, accurate analysis inspection is made by comparing this initial characteristics with each characteristics curve obtained at inspection as required, and finally, the presence of failure of each element is determined with the principle of majority by decision and processing is made. It is efficient to compare the initial operation with the operating conditions of each element only for important period. Further, the accuracy can further be increased by using the value correcting the effect of ambient temperature for the operation value of each element.
