The three-phase relay protection test set is a new type of miniaturized microprocessor-based relay protection test set, developed on the basis of the "Technical Conditions for Microprocessor-Based 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, a true 16-bit DAC module, a new modular high-fidelity high-power amplifier, a large-screen LCD display, and a flexible and convenient rotary mouse controller. The standalone operation already has strong functions and can perform most tests, while connecting to a computer provides even 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, making it convenient to 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 calibration tasks with high automation, such as three-phase differential tests, fast switching of auxiliary power, automatic bus transfer 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 comprehensive multiple protection measures, power soft start, and certain fault self-diagnosis and blocking functions.
Independent dedicated DC power output The device is equipped with a dedicated DC power output of 110V and 220V.
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 sets with the price of small-scale test sets, offering a very high performance-price ratio.
