The new generation of optical digital relay tester. 8 optical port design,and powerful data processing capability can realize full functional test of the optical digital protection devices. It also can simulate
closed-loop test on MU. Equipped with GPS,IRIG - B code synchronization interface and supports
the lEEE1588 to provide the conditions to substation internal debugging and substation to substation
combine debugging.
Software has years of testing experience.It based on powerful test functions and the template function. It integrated the unique functional testing of optical digital protection include: the abnormal SV simulation, virtual terminal test, the optical power testing and so on.Eficient, fast to complete the intelligent station test.
Features:
*8 Fiber Optical Ports for:
· Receiving and sending IEC61850-9-2 and Goose message
· Recelving and sendinglIEEE1588 message
· Measuring received fiber optical power
*Provide flexibility to configure both SV (IEC61850-9-2) and GOOSE ports independently.
*Strong data receiving and sending capability for each fiber optical port:
· Can send 6 groups of SV at the same time
· Can send 15 groups of GOOSE at the sametime
· Can receive 13 groups of GOOSE message
· Can send/receive IEEE1588 message
*While sending SV, the dispersion of the MUis better than±80ns
·Can receive Sv,realizing self-loop test
· Fiber-optic ports can be used to measure received optical power
*8 Independent IEC61869-9(FT3)format SVoutput port
*Can simulate collector and output IEC61869-9 format message to MU
*12 configurable independent low-level analog signal output terminals,can be used to test the
low-level signal input device
*Can publish/subscribe many different GOOSE control block message
*Analyze model file(SCD,ICD,CID,NPI)automatically
· Can configure SV, sample channel message,GOOSE message automatically
· Can check the GOOSE communication link
*SV,GOOSE configure message can be saved and recallrepeatedly
Simulate the abnormal massage (jitter, frame loss, flying spot, wrong sequence, data
anomalies,packet retransmission, channel invalid,out of step, etc.)
* WithlEEE1588 synchronization function and the deviation of the time is less than 80ns
*IRIG-B synchronization port and built in GPS synchronization mechanism
The NF802 can analyze the model files (SCD, ICD, CID, NPI) automatically, for example, configuring SV, sample channel message, GOOSE message automatically, and checking the GOOSE communication link. It can also simulate the abnormal SMV (shake, dropped frames, abnormal data and serial number deviation, etc.). The SMV, GOOSE configuration information can be saved for repeated use. It supports all kinds of digital relay testing, such as, Distance, Differential, Line differential, Auto-reclosing, Directional, Synchronization, Time inversed current/voltage, Frequency relay, Overcurrent/voltage, under voltage, Harmonics, CB Operate, Transplay for comtrade files, etc.
