It can calibrate various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, and simulate various complex instantaneous and conversion faults for whole group testing.
 

1. Flexible combination of voltage and current output can achieve 6-phase voltage and 6-phase current, and can be combined to achieve conventional 4-phase voltage, 3-phase current, 6-phase voltage, 6-phase current, and 12 phase output modes, which are compatible with various traditional testing methods.
2. The single machine operation is convenient. The device panel is equipped with a trackball mouse, optimized keyboard, and a large screen TFT LCD display, with built-in Chinese Windows platform operation software. Ready to use upon startup, easy and fast to operate.
3. In addition to standalone operation, the device can also be connected to an external laptop or desktop computer for operation. The functions of the two methods are the same, providing a truly complete dual operation mode.
4. The output end of the new high fidelity linear power amplifier has always insisted on using high fidelity and high reliability modular linear power amplifiers, rather than switch type power amplifiers. It will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current.
5. The output part of the high-performance host is controlled by DSP, which has fast computing speed, strong real-time digital signal processing capability, wide transmission bandwidth, and controls high-resolution D/A conversion. The output waveform has high accuracy, low distortion, and good linearity. The device adopts a large amount of high-tech and precision component materials, and has undergone specialized structural design, resulting in small size, light weight, comprehensive functions, easy portability, and can work immediately after startup. Flow testing is very convenient.
6. The software has strong functionality and can complete various large-scale complex verification tasks with high automation levels. 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. 6-phase current can facilitate three-phase differential protection testing.
