Alternator DefinitionAn alternator is defined as an AC generator that induces EMF in a stationary wire using a rotating magnetic field, following Faraday’s law of induction.Conditions for Parallel Operation The phase sequence of the incoming machine’s voltage must match the bus bar’s voltage. The RMS line voltage (terminal voltage) of the bus bar or already running machine and the incoming machine should be the same. The phase angle of the two systems should be equal. The frequency of the two te
