In the circuit, such as from the switching transient process (cutting off inductive loads, bouncing relay contacts, etc.), it will usually interfere with other electrical and electronic equipment in the same circuit. This kind of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. Clusters of narrow pulses can charge the junction capacitance of semiconductor devices, which may cause circuit or equipment errors when accumulated to a certain extent. The burst generator determines a common reproducible evaluation basis for evaluating the performance of power supply ports, signal, control and grounding ports of electrical and electronic equipment when disturbed by electrical fast transient bursts. The products meet the requirements of new standards such as iec61000-4-4, en60100-4-4 and gb/t17626.4.

Voltage sag and short-term interruption are caused by the failure of power grid and power facilities or sudden large changes in load. In some cases, there will be two or more consecutive dips or interruptions. Voltage changes are caused by continuous changes in the load connected to the grid. If EUT cannot respond to the change of power supply voltage in time, it may cause faults. The cycle drop generator is used to evaluate the performance of electrical and electronic equipment when subjected to voltage sag, short-term interruption and voltage change. The product meets the requirements of new standards such as iec61000-4-11 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.
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.
