Ready to use upon startup, easy and fast to operate.
3. Dual operation mode, connected to a computer and running through the full set of Chinese operating software on the Windows platform, can perform various large-scale, complex, and highly automated verification tasks. It can easily test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.
4. The software function can complete various large-scale complex verification tasks with high automation level, such as three-phase differential test, plant power fast switching, backup automatic switching test, line protection check synchronous reclosing, etc. It can conveniently test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, online printing reports, etc.
5. The switch quantity contact rich relay protection tester has 8 contact inputs and 4 pairs of empty contact outputs. The input contacts are compatible with empty contacts and 0-250V potential contacts, and can be intelligently and automatically recognized. The input and output contacts can be expanded according to user needs.
6UHV-702 microcomputer relay protection deviceThere is a large LCD display screen. This machine adopts a 320 × 240 dot matrix large screen high-resolution graphic LCD display screen. All operation processes are set on the display screen, and the operation interface and test results are displayed in Chinese, with intuitive and clear display.
