Abstract
A check synchroniser for checking the synchronism between two alternating voltages comprises means for forming pulses corresponding to the frequency and phase of the two voltages to be synchronized, the width of the pulses depending upon the allowable frequency and phase error between the two voltages, the pulses representing the frequencies of the two voltages being wider than the pulses representing the phases of the two voltages, means for comparing the time coincidence between the pulses of both sets and means for indicating when the pulses of both sets partially or completely overlap.
