Relay Protection Test Device Features
Standard 4-phase voltage and 3-phase current output With 4-phase voltage and 3-phase current output, various combined outputs can be conveniently performed for various types of protection tests. Each phase voltage can output 120V, and the three-phase current can output 120A in parallel. The 4th phase voltage Ux is a multifunctional voltage item, which can be set to 4 types of 3U0 or synchronism check voltage, or output any voltage value.
Convenient single-unit operation The single unit is operated by a flexible rotating mouse through a large-screen LCD display, with all Chinese display. It can complete most on-site test and verification work, verify various relays and microcomputer protection devices, and simulate various complex transient and conversion faults for whole-set tests. It can be used immediately after power-on, with convenient and fast operation.
Dual operation modes, connect to computer for operation 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, draw fault waveforms, and print reports online.
Powerful software functions It can complete various large-scale and complex verification tasks with high automation, such as three-phase differential tests, fast switching of plant power, standby power automatic switching tests, line protection synchronism check and reclosing, etc. It can conveniently test and scan various protection settings, perform fault replay, store test data in real time, display vector diagrams, and print reports online.
Rich switch quantity contacts The relay protection tester has 7 contact inputs and 2 pairs of dry contact outputs. The input contacts are compatible with dry contacts and 0-250V potential contacts, and can be intelligently and automatically identified. Three-phase relay protection test device input and output contacts can be expanded according to user needs.
Large-screen LCD display This machine adopts a 320×240 dot matrix large-screen high-resolution graphic LCD display. All operation processes are set on the display screen, and the operation interface and test results are displayed in Chinese, with clear and intuitive display.
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.
Has independent dedicated DC power output The device is equipped with a 110V and 220V dedicated adjustable DC power output.
High cost performance It is a cross-professional joint design product, integrating advanced scientific and technological achievements from multiple disciplines. It combines the performance of large testers with the price of small testers, and has a very high performance-price ratio.
