GDJB-1200A Six Phase Relay Protection Test Set
General Description
GDJB-1200A Six Phase Relay Protection Microcomputer Test Device plays a key role in operating electricity power systems reliably and safely. It is the testing device used in professional field of microcomputer protection, relay protection, excitation measurement, fault recorder.
Features
With Standard 6-phase voltage 6-phase current output, which can test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential power protection and automatic switching devices. The test is more convenient and perfect.
Classic Windows XP operation interface, friendly man-machine interface, easy and quick operation, comes with a recovery function to avoid system crashes caused by illegal shutdown or misoperation. High-performance embedded industrial control computer and 8.4-inch TFT true color display with 800×600 resolution, can provide rich and intuitive information, including equipment current working status and various help information, etc.
The main control board adopts DSP+FPGA structure, 16-bit DAC output, and can generate 2000 high-density sine waves per week for the fundamental wave, which greatly improves the quality of the waveform and the accuracy of the tester.
The power amplifier adopts high-fidelity linear power amplifier, which not only ensures the accuracy of small current, but also ensures the stability of large current.
The USB interface is used to communicate directly with the PC, no need any adapter cables.
Can be connected to a laptop computer (optional) to run.
Equipped with independent dedicated DC auxiliary voltage source output, the output voltage is 110V (1A), 220V (0.6A). It can be used for relays or protection devices that require DC working power.
With software self-calibration function, it avoids the need to open the case to calibrate the accuracy by adjusting the potentiometer, thereby greatly improving the stability of the accuracy.
High-performance embedded industrial control computer and 8.4-inch large-screen high-resolution color TFT liquid crystal display, which can provide rich and intuitive information, including the current working status of the device, next working tips and various help information,
The output uses a high-fidelity, high-reliability modular linear power amplifier instead of a switch-type power amplifier for superior performance. It will not generate high and medium frequency interference to the test site, and it will ensure excellent waveform smoothing and accuracy from high current to small current.
