  • Method of counting electrical load current pulsations
    Patent number: 4184113
    Abstract: A method of counting the number of load current pulsations in an alternating current supply including monitoring the alternations of the supply current and detecting pulsations thereof by detecting suitable falls of the pulsations following the rises thereof, creating upon detecting a pulsation a discrete signal therefor, said signal creation being powered from said pulsation, and counting the discrete signals to determine the number of pulsations.
