Intelligent host:
The host adopts a high-speed and high-performance digital signal processor with fast processing speed and wide transmission frequency band, which can generate high-density fitted sine waves with 360 points per cycle for the fundamental wave. It is currently the highest level among similar output methods;

Single machine independent operation:
HQ-WJ2000 Microcomputer Relay Protection TesterOperated through a large LCD screen using a convenient and flexible rotating mouse, with a complete set of Chinese language displays. It can complete most of the on-site testing and verification work, and can verify various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection. It can also simulate various complex instantaneous, *, and conversion faults for whole group testing;

Connect the computer to run:
Through the complete set of Chinese operating software on the Windows platform (excluding WIN2000), various large-scale, complex, and highly automated verification tasks can be performed. It is convenient to test and scan various protection settings, store test data in real time, display vector diagrams, draw fault waveforms, and print reports online;
