Three-Phase Six-Phase Relay Test Set Relay Protection Tester
This embedded host machine features a large programmed CPLD and can produce 12 channels of D/A output simultaneously. It is designed for field tests and can test both traditional and modern relays, with a main control board using DSP+FPGA architecture and 16 bit DAC output. The machine includes a high-fidelity linear amplifier, 6 voltage outputs, and 6 current outputs, as well as an 8 inch LCD screen, keyboard/mouse and USB ports, and intelligent self-protection. It also has 8 channels of switching value input and 4 channels of switching value output, and plentiful binary and powerful software function, with optional DC power supply.

Advantages of six-phase secondary injection tester compared to single-phase and three-phase:
1. Higher testing efficiency: A 6-phase secondary injection tester can simultaneously test six phases, while single-phase and three-phase testers can only test one or three phases, requiring multiple equipment changes for testing multiple phases and resulting in lower testing efficiency.
2. More comprehensive testing coverage: As a 6-phase secondary injection tester can test six phases, it can cover more testing scenarios and types, including various power protection devices, transformer differential protection, and generator protection.
3. Higher testing accuracy: A 6-phase secondary injection tester utilizes six independent current sources and voltage sources, providing more precise and stable testing signals to ensure testing accuracy and reliability.
4. Better reliability and safety: As a 6-phase secondary injection tester utilizes six independent current sources and voltage sources, it can avoid signal interference and circuit failure, improving the testing equipment's reliability and safety.
