In practical work, power workers need to use microcomputer relay protection testers to test the comprehensive protection devices of switchgear. This device is widely used in the power industry and is well received by everyone. At present, there are many manufacturers and sellers of microcomputer relay protection testers in the market, and the product quality varies. Moreover, there are many types of crisis relay protection testers. So, how should we choose microcomputer relay protection testers? This article will provide a brief introduction for everyone.

 

Flexible combination of voltage and current output, capable of outputting up to six phase voltage and six phase current. It can freely combine traditional four phase voltage, three-phase current type, six phase voltage type, six phase current type, and twelve phase output type. It is not only compatible with traditional testing methods, but also convenient for three-phase transformer differential testing, plant power fast switching testing, and backup automatic input testing. The operation mode includes a 10 inch touch LCD screen and dual operation of keyboard and mouse. The device can also be directly connected to a laptop or desktop computer for convenient, fast, and stable performance.

 

The output terminal of the new high fidelity linear power amplifier has always insisted on using high fidelity and high reliability modular linear power amplifiers, rather than high-performance switching power amplifiers. It will not cause high-frequency interference to the testing site, ensuring excellent waveform smoothing accuracy from high current to low current. The output part of the high-performance host is controlled by DSP, with fast computing speed, strong real-time digital signal processing capability, wide transmission frequency, and high-resolution D/A conversion control. The output waveform has high accuracy, low distortion, and good linearity. Adopting a large number of advanced technologies, precision components, and materials for specialized structural design. Therefore, the device is small in size, light in weight, fully functional, easy to carry, and can work immediately after startup, making it very convenient for flow testing.

 

The software system has more powerful functions and can complete complex verification work for large enterprises with high levels of information automation development. It can easily test and scan various environmental protection settings, process fault playback, store test result data in real time, display vector graphics, and print technical reports online. 6-phase current can facilitate students to conduct three-phase differential protection testing. It has its own independent dedicated DC power output with one 110V and 220V dedicated adjustable DC power output. The complete interface device is equipped with a USB communication port, which can communicate with computers and other external devices. The improved self safety protection ecological function, optimized design of heat dissipation structure, reliable and complete hardware resource protection policy measures, important power soft start function, software self diagnosis method for fault problems, and cultural output locking function.

 

When choosing a microcomputer relay protection tester, you need to consider your actual needs. Therefore, when selecting, choose the equipment that meets your own parameters, and the quality of the equipment needs to be reliably guaranteed.
