(Vertical voltage differential of 6 to 18 electrical degrees). Fixed @ 60 milliseconds is provided to assure that the frequencies of both input lines are sufficiently close to permit paralleling within the preset window. One set N.O., one set N.C. 5 amp resistive at 120 VAC o7 28 VDC Funetion: 25 > ANSI/EEE C37.90-1978 > UL file No. 58048 - CSA file No. LR61158 G @ Application: These relays are designed for automatic paralleling (synchronizing) of generators. The relays sense the phase angle displacement and the amplitude differ- ence between two voltages and permit paralleling only when both voltages are equal and in phase. A short time delay is provided to assure that the frequencies are essentially the same at the moment of paralleling. The basic series is designed to parallel two or more energized AC generators. The Dead Bus type provides paralleling of AC generators to the main bus. They permit electrical connection of an energized generator to an un-energized line (Dead Bus). If the bus is energized, connection of the generator to the bus is permitted only when both are synchronized. ______.
