Abstract

PURPOSE: To sense a trouble beforehand and to improve reliability of the breaker by monitoring any of multiple quantities which vary in operating the breaker, for example, one of differential, integral and instantaneous values with respect to the control current.
CONSTITUTION: Whether the breaker is normal is decided by monitoring a quantity which varies in operating the breaker, for example, the instantaneous value of control current. Respective sampling sites 1 to 4 show that respective quantity levels with respect to time are set as the initial values at the time of products shipment. At this time, a range is given to the time or level and it is determined on considering the variation of test unit errors, surrounding temperature and control voltage. By this way, the wave form of a broken line as shown in figure can be decided abnormal, a trouble is sensed beforehand, resulting in an improvement of reliability of the breaker.
