PARALLEL OPERATION OF ALTERNATORS . The requirements of connecting two alternators in parallel or connecting an alternator to the bus ar. 1. The two effective values of voltages are equal at the terminals being connected. 2. The two frequency are the same 3. The tw o^oltages are exactly opposite in phase (in the local circuit o f the two machine).
