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
themainbus. Theypermitelectricalconnectionofan
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.
