Abstract

PURPOSE:To grasp the rising up time of detecting current accurately while eliminating the error from a ripple current by starting the counting when the detecting current reaches a specific value after the starting, and adding the time up to the count starting. CONSTITUTION:The necessary time after the operation order of a throwing-in or throwing-out of a switch is issued is detected by counting the control pulse current. The pulse currents of the throwing-in and the throwing-off are generated in pulse restoration circuits 8a and 8b respectively, and the counting is stopped when the operation is over respectively. Since the restoration circuits 8a and 8b are formed to issue the rectangular wave when the detected control current comes to be a specific value I rel larger than the ripple current after the starting, the error detection from the ripple current at the starting time is prevented. The time T0 from the starting of the control current to a specific value I rel can be found simply experimentally. By adding the time T0, the operation time of the switch can be counted accurately.
