ABSTRACT:
A load measuring device includes a sensor for detecting power consumption surges by detecting a zero voltage point in the alternating voltage of an electrical apparatus, detecting the zero current point in the alternating current of the apparatus least remote in time from the detected zero voltage point, and measuring the interval between the two zero points. The zero-current point is detected by a current sensor which comprises a first rectifier coupled in series with the apparatus, a second rectifier coupled in parallel opposition with the first rectifier, and a voltage sensor coupled in parallel with both rectifiers.
