Compressor surge is a low-frequency and high-amplitude shock phenomenon of the air that along the axial direction of the compressor, it will cause strong mechanical vibration of the compressor part and over-temperature, it will cause damage to the parts or the whole in a short time. So the surge test of the compressor is particularly important. This article introduced a surge test system that based on the LXI bus, and describes the main features and advantages of this system. In the test, acquired and recorded the voltage, temperature and pressure signal. It is validated that the system can send the signals quickly when the surge occurred, reaching the purpose of the construction and can effectively prevent the damage to the test components.
