The NPG800 / NPG800R relays protect the synchronous generators connected to three-phase networks, whatever the type of machine:
steam, hydraulic and gas turbines, diesel and gas engines.
ANSI functions for NPG800 / NPG800R:
21 / 24 / 27 / 32RP / 32P / 32Q / 37P / 37Q / 40 / 46 / 49 / 50 / 50V / 51 / 51V / 59 / 59N / 64 / 81 / 86 / 74TC / 50BF
These relays are part of the NP800 range, offering multi-function protection and communication via Modbus (RS485) or Modbus TCP (Ethernet). A full brochure is available on the NP800 range page
