The DEIF G59 protection relay package is used for safety and regulation of generators. This unit is tested for the safety of concurrent generators, operating simultaneously along with the mains.
The G59 has a 3 - phase safety under and over voltage with a connected vector shift and ROCOF ( df / dt). The G59 guarantees no haphazard reconnection and has a quick decoupling capability of the generator. The G59 processes data digitally.
