GDJB six-phase relay protection tester is an advanced power test equipment, specially designed for calibrating and testing relay protection devices in six-phase power systems. This equipment adopts an advanced structure that can be operated independently or connected to a laptop computer. It can simulate various power system fault conditions and provide accurate test results to ensure the reliability and accuracy of the relay protection system.
1. Embedded host, equipped with large programmable CPLD (complex programmable logic device);
2. Single machine outputs 12 channels of D/A at the same time; high-precision linear power amplifier, 6 voltage outputs and 6 current outputs;
3. Easy to carry, meeting all requirements of field testing. Digital signal processor microcomputer. Not only can it test traditional relays and protectors, but also modern microcomputer relays, especially suitable for transformer differential protection and conversion equipment.
4. Two sets of DC power supply, 110VDC/1.0A&220VDC/0.6A, no need to set and adjust through software (optional)
5. The main control board is DSP+FPGA architecture, 16-bit DAC output, and generates a high-density sine wave of 2000 points per circle for the fundamental wave, which greatly improves the waveform quality and the accuracy of the test instrument.
6. Adopt high-fidelity linear amplifier. It not only ensures the accuracy of small currents, but also ensures the stability of large currents.
7. 8-inch LCD display. Provides keyboard/mouse connection port, 2 USB ports, 2 RS232 ports, can communicate with PC and other communication devices;
8. 10 switch inputs, 8 switch outputs, input contacts are optional for empty contacts and 0-250V potential contacts, intelligent identification;
9. Rich binary and powerful software functions;
10. Intelligent self-protection;
