It can calibrate various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, and simulate various complex instantaneous and conversion faults for whole group testing

1. The intelligent host adopts a high-speed and high-performance digital signal processor with fast processing speed and wide transmission bandwidth. The software applies a dual precision algorithm to generate high-precision waveforms for each phase. Due to the use of an integrated structure, the various parts are tightly combined, the data transmission distance is short, and the structure is compact.

2. The standalone independent operation device is operated by a convenient and flexible rotating mouse through a large LCD screen, with Chinese display. 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.

3. It can complete various large-scale complex verification tasks with high automation level, such as differential testing, backup automatic switching testing, line protection check synchronous reclosing, etc. It can conveniently test and scan various protection settings, store test data in real time, display vector graphics, etc.

4. Large screen LCD display: This machine adopts a high-resolution graphic LCD display with a large screen. The operation process is set on the display screen, and the operation interface and test results are displayed in Chinese, making the display intuitive and clear
