External adjustment for field sensing of 10-30% of

nominal input voltage. (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.

Function:

•

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.
