This intelligent substation optical digital relay protection tester is a relay protection test device implemented using new computer technology.

1. Support intelligent testing template editing, add testing items during the testing process, and save them as reusable testing engineering files to improve testing efficiency in the later stages of calibration and defect elimination;
2. Equipped with digital protection automatic testing function, it can complete most testing items of a single protection device with one click;
3. It can test the merging units, protection, measurement and control devices, and intelligent terminals of digital substations;
4. Equipped with message recording and analysis functions, providing quick assistance for on-site fault diagnosis;
5. Support manual or automatic testing of amplitude, phase, frequency, impedance, vector, sequence, and power, as well as automatic variation testing using gradient, slip, and synthesis methods;
6. Support virtual terminal graphical display function, with clear and concise data flow direction;
7. Supports FT3, FT3 extension, DL/T 282 message output, and supports 2M/4M/6M/8M/10M baud rate UART encoding and 5M/10M/20M Manchester encoding;
8. Support fault simulation and PCAP/COMTRADE format data playback function;
9. Equipped with MMS fixed value reading and writing function, capable of reading and writing configuration information such as intelligent IED device fixed values;
10. It has synchronous triggering function, supports GPS/BD timing, IRIG-B, PPS, and IEEE1588 (PTP) timing modes, and can output IRIG-B, PPS, and IEEE1588 (PTP) timing signals externally;
11. Support simultaneous output of 8 timing signals;
