Product description

Performance characteristics

• The standard 4-phase voltage and 3-phase current output has a 4-phase voltage and 3-phase current output, which can conveniently perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current triple can output 120A. The fourth phase voltage Ux is a multifunctional voltage item, which can be set to four types of 3U0 or synchronous voltage detection, or output under any certain voltage value.

• Single machine operation is convenient. The single machine is operated through a large LCD screen with a convenient and flexible rotating mouse, all displayed in Chinese. Can complete most of the on-site testing and verification work, can verify various relays and microcomputer protection, and can simulate various complex instantaneous, permanent, and conversion faults for the entire set of tests. Ready to use upon startup, easy and fast to operate.

• Dual operation mode, connected to the computer and running through a complete set of Chinese operation software on the Windows platform, can perform various large-scale, complex, and more automated verification tasks. It can conveniently test and scan various protection settings, store test data in real-time, display vector maps, draw fault waveforms, and print reports online.

• The software has powerful functions and can complete various large-scale and complex verification tasks with high automation, such as three-phase differential testing, factory power fast switching, backup automatic switching testing, line protection inspection and synchronous reclosing, etc. It can conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector maps, and print reports online.

• The relay protection tester has rich switch contacts, with 8 contact inputs and 4 pairs of air contact outputs. The input contact is empty and compatible with the 0~250V potential contact, which can be intelligently and automatically recognized. Input and output contacts can be expanded according to user needs.

• The large screen LCD display screen adopts 320 × 240 dot matrix large screen high-resolution graphic LCD display screen, all operation processes are set on the display screen, the operation interface and test results are displayed in Chinese, and the display is intuitive and clear.

• Self protection adopts a reasonably designed heat dissipation structure, with reliable and comprehensive multiple protection measures, power soft start, and certain fault self-diagnosis and locking functions.

• Equipped with an independent dedicated DC power output device with a dedicated adjustable 110V and 220V DC power output.

• High cost-effectiveness is a cross disciplinary joint design product that integrates advanced technological achievements from multiple disciplines. Having both the performance of large testers and the price of small testers, it has a high performance to price ratio.
