Relay protection tester, English name: Relay protection tester. The host adopts a high-speed and high-performance digital signal processor with fast operation speed and wide transmission frequency band, which can generate high-density fitted sine waves of 360 points per cycle for the fundamental wave. This is the highest level among similar output methods. The waveform has high fidelity and low distortion, especially in harmonic output, even for 6th harmonic and 300Hz, it can achieve a high density of 68 point D/A per week. It is a new type of intelligent testing instrument. Previously, tools were mainly composed of voltage regulators and phase shifters, which were bulky and had low accuracy, and could no longer meet the calibration requirements of modern microcomputer relay protection. With the continuous development of science and technology, it has been widely used in various fields such as line protection, differential protection of main transformers, excitation control, etc. The comprehensive automation of substations has become the mainstream. The product application relay protection microcomputer testing device is an important testing tool to ensure the safe and reliable operation of the power system. With the rapid development of computer technology, microelectronics technology, and power electronics technology, the application of the latest technological achievements to continuously introduce new high-performance relay protection testing devices is an inevitable trend of technological progress
