Integration Adaptive Fast Response Relay Tester 3 Phase Relay Tester

What problems does it solve?

It performs one-stop testing on everything from traditional electromagnetic relays to modern microprocessor-based protection devices. Whether handling complex transformer differential protection, automatic switchover device (standby auto-switching) debugging, or simple voltage/current relay calibration, it works effortlessly to ensure grid safety and stability.

Advantages

• Integrated Design, Easy Operation： With a built-in Windows XP OS, 10.4-inch true-color display, and industrial-grade keyboard/mouse, it operates independently without an external PC—ready to use at power-on.

• Ultra-High Precision & Stability： DSP+FPGA core control and 16-bit DAC output generate 2000 high-density sine points per cycle, ensuring low-current accuracy and high-current stability. Linear amplifier technology eliminates switching interference for pure waveforms.

Features

1. Powerful Software Modules： Over 20 specialized test modules including AC, DC, frequency, differential, impedance ladder, and state sequence, covering all protection types (lines, transformers, generators, etc.).

2. Complete Hardware Interfaces： 8 switchable inputs, 4 switchable outputs, and an independent 110V/220V DC auxiliary voltage source (110V/1A, 220V/0.6A) to directly power protection devices.

3. Safety & Recovery： The Windows XP system includes a one-key recovery function to prevent crashes from improper shutdowns or misoperations.
