Lightning Impulse Voltage Test System for High Voltage Equipment – 1.2/50 μs Impulse Generator with Automatic Control, Digital Measurement and Waveform Analysis

The Lightning Impulse Voltage Test System is a complete high-voltage laboratory solution designed to evaluate the impulse withstand performance of electrical insulation.

Unlike a standalone impulse generator, a complete test system integrates:

• High-voltage impulse generator
• Charging power supply
• Control system
• Voltage divider
• Measurement system
• Digital recorder
• Waveform analysis software
• Safety interlock system
• Wave-shaping components

This integrated architecture helps customers establish a complete and repeatable impulse testing workflow.

Lightning Impulse

1.2/50 μs standard lightning impulse testing.

Chopped Impulse

Testing insulation under chopped-wave conditions.

Switching Impulse

For applicable high-voltage and UHV equipment.

Automatic Measurement

Measurement of:

• Peak voltage
• Front time
• Tail time
• Chopping time
• Waveform parameters

Digital Analysis

• Real-time waveform display
• Waveform storage
• Test data recording
• Automatic evaluation
• Test report generation

Ideal for:

• Transformer manufacturers
• GIS manufacturers
• HV switchgear manufacturers
• Cable manufacturers
• Insulator manufacturers
• Power utilities
• HV testing laboratories
• Research institutes
• Universities

Safety: High-voltage impulse testing requires coordinated control, grounding and interlocking.

Accuracy: The measuring chain needs to be designed for fast transient signals.

Repeatability: Stable charging and controlled triggering are important for repeatable test results.

Documentation: Customers increasingly need digital waveform records and traceable test reports.

IEC 60060-2:2025 specifically addresses measuring systems used for lightning and switching impulse voltage measurements.
