High Voltage Impulse Generator 200kV–6000kV – Lightning Impulse Test System for Transformer Insulation Withstand and High Voltage Equipment Testing
Product Description
The High Voltage Impulse Generator is an advanced impulse voltage test system for generating controlled high-voltage impulses used in electrical insulation testing.
The system can be engineered in different voltage and energy ratings, making it suitable for both medium-voltage equipment testing and large-scale high-voltage laboratory applications.
Depending on the configuration, the system can provide lightning impulse, chopped lightning impulse and switching impulse voltage tests for transformers and other high-voltage electrical equipment.
Multi-stage impulse generators provide flexible voltage and energy configurations, allowing the equipment to be adapted to different laboratory requirements and test objects.
Testing Functions
Lightning Impulse Test
Generates standardized lightning impulse voltage to evaluate the ability of insulation systems to withstand lightning-related transient overvoltage.
Chopped Wave Test
Used to evaluate insulation behavior under chopped impulse conditions where the impulse waveform is interrupted by a chopping device.
Switching Impulse Test
Used for high-voltage equipment applications where switching overvoltage conditions need to be simulated.
Insulation Withstand Test
Evaluates whether the insulation system can withstand specified impulse voltage without unacceptable insulation failure.
Dielectric Breakdown Research
Can be used in research applications to study insulation breakdown, discharge behavior and insulation coordination.
Application Equipment
The high-voltage impulse test system can be used for:
- Power transformers
- Distribution transformers
- Instrument transformers

Why Choose a High Voltage Impulse Test System?
For large transformer and high-voltage equipment manufacturers, impulse testing is not simply about generating a high voltage. The complete system needs to provide controlled charging, reliable triggering, accurate waveform measurement and repeatable test results.
The system can therefore be configured as a complete testing platform including:
- Impulse voltage generator
- Charging power supply
- Wave-shaping resistors
- Chopping device
- High-voltage capacitors
- High-voltage divider
- Measurement system
- Control system
- Data acquisition
- Test software
- Safety interlock system

Customer FAQ
How do I select the right impulse generator voltage?
The required voltage depends mainly on the rated voltage of the test object, applicable testing standard, insulation level and required test procedure.
Is higher voltage always better?
No. The generator should be selected according to the actual test requirement. Voltage level, energy, capacitance, waveform and load characteristics all need to be considered.
Can you provide 1000kV or higher impulse generators?
Yes. High-voltage impulse systems can be engineered for very high voltage laboratory applications. Some industrial systems are available in the megavolt range.
Can the impulse generator be integrated with an automatic measurement system?
Yes. A complete system can integrate the generator, voltage divider, oscilloscope/data acquisition equipment and control software.
What determines the energy requirement?
The required energy is related to the generator configuration and test object characteristics. For large-capacitance test objects, sufficient stored energy and appropriate circuit design are particularly important.
