voltage dips/sags, short interruptions are caused by failures of the power grid and power facilities or sudden large changes in loads. in some cases, there will be two or more consecutive dips or interruptions. voltage changes are caused by continuous changes in the loads connected to the grid. if the eut cannot respond in time to changes in the power supply voltage, it may cause malfunctions. voltage dips generators are used to evaluate the performance of electrical and electronic equipment when subjected to voltage dips/sags, short interruptions, and voltage changes. products fully meet the requirements of standards iec/en 61000-4-11 and gb/t17626.11.
the impact of lightning (indirect lightning) in nature and voltage changes caused by large switch switching in power supply lines on power supply lines and communication lines is particularly large, and the impact on products may be destructive. the lightning surge generator is used to evaluate the performance of the equipment when it is subjected to high-energy disturbance from the power line port and other signal line ports. the product meets the requirements of new standards such as iec61000-4-5 and gb/t17626.5.
the lightning surge generator sur 20ka is used to inspect the anti surge protection devices such as zinc oxide arrester valve piece, varistor, spd, tvs tube, gas discharge tube, etc. for surge impact test. the product produces 8/20us surge pulse waveform, and the technical indicators of the waveform comply with the provisions of national standards and iec standards.
