Product Description
The Lightning Impulse Generator is a high-performance high-voltage test system designed to simulate the transient overvoltage stress caused by lightning strikes and evaluate the dielectric withstand capability of electrical equipment.
The system generates standardized lightning impulse voltage waveforms and can be configured for full-wave and chopped-wave testing. Depending on the application and system configuration, switching impulse testing can also be supported.
Modern impulse voltage systems typically integrate the impulse generator, DC charging unit, voltage divider, control system, digital measurement system and waveform analysis software into one complete laboratory solution.

Customer Pain Points
“How can I prove that my equipment can withstand lightning overvoltage?"
The system provides a controlled laboratory environment to apply standardized impulse voltage and evaluate insulation performance before equipment is put into service.
“How can I meet international testing standards?"
The system can be designed around applicable IEC/IEEE/customer test requirements. IEC 60060-1:2025 specifically covers dielectric tests using impulse voltage.
“How can I obtain reliable test records?"
An integrated digital measurement and analysis system can capture the impulse waveform and calculate key parameters for documentation.
FAQ
Q: What is the standard lightning impulse waveform?
The commonly used standard lightning impulse is 1.2/50 μs, with the applicable tolerances defined by the relevant high-voltage test standard.
Q: Can the generator produce positive and negative impulses?
Yes, depending on system configuration and polarity-switching design.
Q: Can it perform chopped-wave testing?
Yes. A chopping gap/accessory system can be configured for chopped lightning impulse testing.
Q: What voltage level can be supplied?
The voltage rating is project-specific and can range from laboratory-level systems to multi-megavolt impulse generators. Commercial systems currently cover configurations from hundreds of kV to several MV.
