GDJB-1200A Six Phase Relay Protection Test Set
● Output up to 6-phase voltage 6-phase current, which can be combined to realize conventional 4-phase voltage 3-phase current type, 6-phase voltage type, 6-phase current type, and 12-phase output mode.
● 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.
● The output part is controlled by DSP, which has fast calculation speed, strong real-time digital signal processing capability, transmission bandwidth and high-resolution D/A conversion. The output waveform has high precision, small distortion and good linearity. It adopts a large number of advanced technologies and precision component materials, and has carried out professional structural design. Therefore, the device is small in size, light in weight, full in function, easy to carry, and can be operated once start up, and the test is very convenient.
● It can complete a large number of large-scale complex verification work with high degree of automation. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online.
● There is an independent 110V and 220V dedicated adjustable DC power output for on-site inspection.
● The new generation GDJB-1200A tester is equipped with 10-way opening and 8-way opening, which is convenient for self-injection test. The input contact is compatible with an empty contact and 0~250V potential contacts, which can be intelligently and automatically recognized.
● Can perform a variety of complex calibration tasks, and can easily test and scan various protection settings for fault playback. Store test data in real time, display vector graphics, print reports, etc.
● The heat dissipation structure is designed reasonably, the hardware protection measures are reliable and perfect, and the power soft start function, software self-diagnosis and output blocking function are provided.
