Products family : Automatic Synchronizer Relay
Sector : Generation, Industry
NPRG860 & NPRG870 perform synchronization and paralleling of generators with electrical network.
NPRG860 features a speed adjustment function. NPRG870 adds a voltage adjustment function. These two devices also include CB time compensation allowing paralleling without phase shift.
As well as the usual protection functions, NP800 relays provide monitoring, measurement and recording of the electrical quantities of the network.
