The mains decoupling relay - type G59 package – forms part of a complete DEIF series of relays for the protection and control of generators. This package is applied for the protection of synchronous generators, running in parallel with the mains.

Features include
•    Combined vector shift and ROCOF (df/dt)
•    Protection of over-/underfrequency
•    3 phase protection of over-/undervoltage
•    Digital data processing
•    Fast decoupling of the generator
•    Ensures no asynchronous reconnection
