News Details

The three-phase relay protection test set is a new type of miniaturized microcomputer relay protection test set, developed on the basis of the "Technical Conditions for Microcomputer Relay Protection Test Devices (Discussion Draft)" issued by the Ministry of Electric Power, widely listening to user opinions, summarizing the advantages and disadvantages of similar domestic products, and fully utilizing modern advanced microelectronic technology and devices. It adopts an advanced structure that can operate independently as a standalone unit or be connected to a laptop computer for operation. The host is equipped with a new generation high-speed digital signal processor microcomputer, a true 16-bit DAC module, a new modular high-fidelity high-power amplifier, a large-screen LCD display, and a flexible and convenient rotating mouse controller. The standalone operation already has strong functions and can perform most tests, while connecting to a computer provides more powerful operational functions. It is small in size and high in precision.

Product Features of Three-Phase Relay Protection Test Set

Dual operation modes, connected to computer for operation  Through the full set of Chinese operating software on the Windows platform, various large-scale, complex, and highly automated calibration tasks can be performed, various protection settings can be easily tested and scanned, test data can be stored in real-time, vector diagrams can be displayed, fault waveforms can be drawn, and reports can be printed online.

Powerful software functions  It can complete various large-scale and complex calibration tasks with high automation, such as three-phase differential tests, plant power fast switching, backup 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 reports online.

Rich switch quantity contacts  It has 7 contact inputs and 2 pairs of empty contact outputs. The input contacts are compatible with both empty contacts and 0-250V potential contacts, and can be intelligently and automatically identified. Input and output contacts can be expanded according to user needs.

Large-screen LCD display  This device uses 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, making the display intuitive and clear.

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.

Independent dedicated DC power output  The device is equipped with a 110V and 220V dedicated DC power output.

High cost-performance ratio  It is a cross-disciplinary joint design product that integrates advanced scientific and technological achievements from multiple disciplines. It combines the performance of large-scale test instruments with the price of small-scale test instruments, offering a very high performance-price ratio.
