Six phase microcomputer relay protection tester

1Six phase microcomputer relay protection testerKey Features:

The flexible combination of voltage and current output can achieve 6-phase voltage and 6-phase current, and can be combined freely to achieve conventional 4-phase voltage, 3-phase current type, 6-phase voltage type, 6-phase current type, and 12 phase output modes. It is compatible with various traditional testing methods, and can also be conveniently used for three-phase transformer differential testing, plant power fast switching, and backup automatic switching testing.

The operation mode device can be directly connected to a laptop or desktop computer for convenient, fast, and stable performance.

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, for improved performance. It will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current throughout the entire process.

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 number of advanced technologies 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.

The software has powerful functions 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.
