Flexible combination of voltage and current outputs: It can output up to 6-phase voltage and 6-phase current, and can be arbitrarily combined to achieve conventional 4-phase voltage and 3-phase current, 6-phase voltage, 6-phase current, and 12-phase output modes. It is compatible with various traditional test methods and can also conveniently conduct three-phase transformer differential tests, plant power fast switching, and backup power automatic switching tests.
2. Operation method: The device can be directly connected to an external laptop or desktop computer for operation, which is convenient, fast, and stable in performance.
3、New high-fidelity linear power amplifier: The output end consistently adopts a high-fidelity, high-reliability modular linear power amplifier instead of a switching power amplifier, ensuring reliable performance. It does not generate high or medium frequency interference at the test site, and guarantees smooth waveform and excellent accuracy from large currents to tiny currents throughout the entire process.
4、High-performance host: The output part adopts DSP control, with fast computing speed, strong real-time digital signal processing capability, wide transmission bandwidth, and control of high-resolution D/A conversion. The output waveform has high precision, low distortion, and good linearity. A large number of new technologies and reliable component materials are adopted, and professional structural design is carried out, so the device is small in size, light in weight, full in function, and easy to carry. It can work immediately after power-on, making mobile testing very convenient.
5、Powerful software functions: It can complete various large-scale and complex calibration tasks with high automation, conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector diagrams, and print reports online. The 6-phase current can conveniently conduct three-phase differential protection tests.
6、Dedicated DC power output: It is equipped with one 110V and one 220V dedicated adjustable DC power output.
