The flexible combination of voltage and current output can achieve a 4-phase voltage and 3-phase current output mode, which can be combined in various ways to achieve the conventional 4-phase voltage and 3-phase current output mode. 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 amplifier has always insisted on using high fidelity and high reliability modular linear amplifiers instead of switch type amplifiers, which have good 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 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. It is convenient to conduct three-phase differential protection testing.
It has an independent dedicated DC power output with one 110V and 220V dedicated DC power output.
The complete interface device is equipped with a USB communication port, which can communicate with computers and other external devices.
The sound self-protection function of the cooling structure design is reasonable, the hardware protection measures are reliable and complete, and it has functions such as power soft start, software self diagnosis of faults, and output locking.
