<p>PURPOSE: To reduce or eliminate an interference voltage, generated in the winding of an alternator by providing a differential signal amplitude discriminator for performing discrimination between at least a pair of phase signals transmitted from an alternator. CONSTITUTION: A detection circuit is provided with a differential discriminator 1 for performing the discrimination of the amplitude of at least a pair of phase signalsϕ1 ,ϕ2 transmitted from an alternator. Also, it is provided with at least two input terminals 11, 12 separately connected to the first phaseϕ1 and the second phaseϕ2 of a multi-alternator, to accept either one of the phasesϕ1 ,ϕ2 of the alternator. Further, it is provided with a threshold comparator 13 for generating a signal s f r a for displaying the operating state of the alternator, when the amplitude differenceϕ1 -ϕ2 of the phase signal of the alternator exceeds a given thresholds.</p> |
