Abstract
PURPOSE: To secure an accurate time error measurement for the operation time measurement of the breaker or the like even though some potential difference exists between the input signals by introducing one of the plural number of the input signals into the gate control circuit via the insulating circuit.
CONSTITUTION: When start signal (b) is applied to insulating circuit 7 from start input signal lines 31 and 32, the signal obtained at the output side of the photo coupling circuit is supplied to gate control circuit 5. Thus signal (a) obtained by dividing 2 the output of reference oscillator 1 is supplied to counter 6 via circuit 5 to be counted. Then with application of stop signal (c) to stop input signal lines 41 and 42, circuit 5 is closed to stop the supply signal to counter 6. As a result, the time difference between signals (b) and (c) can be measured based on the count value of counter 6.
