SC-802 microcomputer relay protection tester

FEATURES

• The 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.
• By connecting to a computer and running a complete set of Chinese operating software on the Windows platform, various large-scale, complex, and highly automated verification tasks can be carried out. It is convenient to test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.
• The machine adopts a large screen high-resolution graphic LCD display, and all operation processes are set on the display screen. The operation interface and test results are displayed in Chinese, making the display intuitive and clear.
• The "foolproof" operation adopts an advanced controller "rotating mouse", greatly simplifying the structure of the operation part, making the operation simple, fast, and easy to master.
• The new high fidelity power amplifier output stage adopts a new high-power modular high fidelity power amplifier component, which can be used for both current output and voltage output, with high output power, good accuracy, and high reliability.
• The current and voltage are directly output as phase voltage and phase current using a DC power amplifier output method, which can directly output AC voltage, AC current, DC voltage, and DC current, with variable angles and frequencies, and can superimpose 1-20 harmonics.
• Self protection adopts a reasonably designed heat dissipation structure, with reliable and complete multiple protection measures, power soft start, and certain fault self diagnosis and locking functions.
• There is an independent dedicated DC power output device with one 110V or 220V dedicated DC power output.
• Rich contacts with 7 input contacts and 2 output contacts. The input contacts are compatible with both empty contacts and 0-250V potential contacts, and can be intelligently and automatically recognized.
• The integrated single machine structure of the host adopts AC 220V power supply for operation. Small size, light weight, easy to carry, and convenient for flow testing.
• High cost-effectiveness belongs to cross disciplinary joint design products, which integrate advanced technological achievements from multiple disciplines. Combining the performance of a large testing instrument with the price of a small testing instrument, it has a high cost performance ratio.
