Description
NF802 is the new generation of digital relay test equipment with local control. This digital relay test set is equipped with 8 optical ports, and its powerful data processing capability can achieve the full functional test of the IEC61850 devices. NF802 is also equipped with Windows and PowerTest software inside, so you can do operation and see the results without using PC/Laptop.
Features:
· 8 fiber optical ports for: Receiving and sending IEC61850-9-2 format SV and GOOSE message; Receiving and sending IEE 1588 message; Measuring received fiber optical power.
· Provide flexibility to configure both SV (IEC61850-9-2) and GOOSE ports independently.
· 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.
· Windows and PowerTest software inside.
