NF802 is the new generation of digital relay test equipment with local control. This digital relay tester is equipped with 8 optical ports, and its powerful data processing capability can achieve the full functional test of the IEC61850 devices. Support GPS\ IRIG-B\ IEEE 1588 synchronization, it makes the substation internal debugging and substation to substation combine debugging available. NF802 integrated some unique functions including: the abnormal SVGOOSE simulation, virtual terminal test, the optical power testing and so on.


  • 8 fiber optical ports for:Receiving and sending IEC61850-9-2 format SV and GOOSE message;Receiving and sending IEE1588 message;Measuring received fiber optical power
  • Provide flexibility to configure both SV (IEC61850-9-2) and  GOOSE ports independently.
  • Local control with quick control buttons
  • Each port can be configured as Receive and Send at the same time or it can be configured as Receive or Send.
  • Can check the GOOSE communication link
  • SV, GOOSE configure message can be saved and recall repeatedly 
  • With the IEEE1588 synchronization function, deviation of the time is less than ±80ns
  • With GPS, IRIG-B code synchronization interface.
