200kV Rated Impulse Voltage Generator with 1.2/50μs Lightning Impulse and Mobile Integrated Design for Transformer Testing

The Chopped Lightning Impulse Test System provides both standard full-wave lightning impulse and controlled chopped-wave testing.

Chopped-wave testing is used where the test specification requires insulation to withstand a lightning impulse that is interrupted by a controlled breakdown/chopping event.

• Full lightning impulse
• Chopped lightning impulse
• Positive impulse
• Negative impulse
• Controlled chopping
• Waveform measurement
• Chopping time measurement
• Peak voltage measurement
• Digital waveform analysis

• Transformer testing
• Bushing testing
• Insulator testing
• GIS testing
• Switchgear testing
• Cable accessory testing

Customers frequently ask:

“Can one system perform both full-wave and chopped-wave testing?"

Yes, with the appropriate chopping-gap and control configuration.

“Can the chopping time be measured automatically?"

A suitable digital impulse measurement system can capture and analyze the chopping event.

“Will the waveform meet the required standard?"

The generator and measuring system should be engineered and verified against the customer's applicable standard and test specification.
