SC-802 microcomputer relay protection tester

Function and purpose:

SC-802 microcomputer relay protection testerIn addition to being able to 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, it can also simulate transient, transient, and conversion faults from single-phase to three-phase for whole group testing. It can also complete various highly automated large-scale complex verification tasks, automatically test and scan various protection settings, store test data in real time, display vector graphics, and print reports online.

Technical features:

★SC-802 microcomputer relay protection testerThe intelligent host adopts a high-speed and high-performance digital signal processor with fast processing speed, wide transmission frequency band, and software application of dual precision algorithm to generate high-precision waveforms of 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.
The standalone independent operation device is operated by a convenient and flexible rotating mouse through a large LCD screen, with a complete set of Chinese 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 the complete set of Chinese operating software on the Windows platform, which can perform various large-scale, complex, and highly automated verification tasks. It can easily test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.
★ Large screen LCD display: This machine adopts a high-resolution graphic LCD display with a large screen. 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.
