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.
