The pulsed magnetic field is generated by lightning strikes on buildings and other structures (including antennas, grounding bodies and grounding grids), as well as the initial transient of faults in low-voltage, medium voltage and high-voltage power systems. It can also be generated when the disconnector in the high-voltage substation is connected with the high-voltage bus. The product meets the requirements of IEC 61000-4-9 and gb/t 17626.9 new standards.

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.
