Ringing wave is caused by the switching of power supply and control line or lightning strike, and appears on the terminal of the equipment. Ringing wave may affect the reliable operation of equipment and system. The ringing wave generator is used to evaluate the performance of electrical and electronic equipment, devices or systems subjected to ringing waves. The product meets the requirements of new standards such as iec61000-4-12 and gb/t17626.12.
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 lightning surge generator sur 6ka 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.
