I. Main Features of the Product

      1. Standard4-phase voltage and3-phase current output: With4-phase voltage and3-phase current output, various combinations can be conveniently performed for various types of protection tests. Each phase voltage can output120V, and the three-phase current can output120A. The fourth phase voltageUxis a multifunctional voltage item, which can be set to4types of3U0or synchronization voltage, or output at any specific voltage value.

      2. Convenient single-unit operation: The single unit is operated via a flexible rotating mouse through a large LCD screen, with all displays in Chinese. It can complete most on-site test and verification tasks, verify various relays and microcomputer protections, and simulate various complex transient, permanent, and converting faults for complete group tests. It is ready to use upon power-on, with quick and convenient operation.

      3. Dual operation modes, connectable to a computer: Through the full set of Chinese operation software on the Windows platform, it can perform various large-scale, complex, and highly automated verification tasks, conveniently test and scan various protection settings, store test data in real-time, display vector diagrams, plot fault waveforms, and print reports online.

      4. Powerful software functions: It can complete various highly automated and complex verification tasks, such as three-phase differential tests, auxiliary power fast switching, standby power automatic switching tests, line protection synchronization and reclosing tests, etc. It can conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector diagrams, and print test data online.

      5. Rich switch quantity contacts: The relay protection tester has7input contacts and2pairs of empty output contacts. The input contacts are compatible with both empty contacts and0～250Vpotential contacts, with intelligent automatic recognition. Input and output contacts can be expanded according to user needs.

      6. Large-screenLCDdisplay: This unit adopts a320×240dot-matrix large-screen high-resolution graphic LCD. All operation processes are set on the display, and the operation interface and test results are displayed in Chinese, with clear and intuitive display.

      7. Self-protection: It adopts a reasonably designed heat dissipation structure, and has reliable and complete multiple protection measures and power soft start, as well as certain fault self-diagnosis and blocking functions.

      8. Independent dedicated DC power output: The device is equipped with one110V and 220Vdedicated adjustable DC power output.

      9. High cost-performance ratio: It is a joint design product, integrating numerous advanced scientific and technological achievements. It combines the performance of large testers with the price of small testers, offering a very high cost-performance ratio.
