Product Overview
The Multi-Waveform Lightning Impulse Generator is designed for high-voltage testing applications that require different impulse voltage waveforms. Depending on the selected configuration, the system can generate standard lightning impulse full waves, chopped waves, and switching impulse waveforms.
This flexibility makes it suitable for laboratories that test multiple types of high-voltage equipment or conduct test programs requiring different impulse conditions.
The system can be engineered with an impulse generator, charging unit, wave-shaping resistors, chopping equipment, switching impulse components, voltage measuring divider, digital waveform recorder, and control system.
The available waveforms, output ratings, and performance must be confirmed against the required test program.

Testing Functions
1. Full-Wave Lightning Impulse Testing
Generates the specified lightning impulse waveform, commonly 1.2/50 μs where required, for insulation withstand evaluation.
2. Chopped-Wave Testing
Uses a compatible chopping arrangement to produce the required chopped impulse waveform. Chopping time and other parameters must be selected according to the test specification and system design.
3. Switching Impulse Testing
A dedicated switching impulse configuration can be provided for applications requiring longer-duration impulse voltage waveforms.
4. Waveform Measurement and Analysis
The configured measurement system captures impulse waveforms and supports analysis of the relevant peak voltage and timing parameters.
5. Test Configuration Management
A suitable control system can support repeatable test settings and data recording, depending on the software and automation functions selected.
Applications
- Power transformer insulation testing
- GIS and high-voltage switchgear testing
- High-voltage bushing testing
- Insulator and insulator-string testing
- Selected extra-high-voltage equipment testing
- High-voltage laboratory research
- Manufacturer type-testing facilities
Why Choose a Multi-Waveform System?
Greater test flexibility: One appropriately configured system can support multiple test requirements.
Reduced configuration uncertainty: Waveform requirements are considered during system design rather than after equipment delivery.
Integrated measurement: Compatible measuring and recording equipment can be specified as part of the complete solution.
Application-specific engineering: The system can be configured according to the equipment under test, laboratory layout, and required standards.
Frequently Asked Questions
Q1: What is the difference between a full-wave and a chopped-wave impulse?
A full-wave impulse follows the specified impulse waveform without intentional chopping. A chopped-wave impulse is interrupted at a defined point using a suitable chopping arrangement. Each is used according to the applicable test procedure.
Q2: Can switching impulses be generated by the same system?
A suitable system can support switching impulses when the necessary circuit, wave-shaping components, and measurement configuration are included.
Q3: Are all three waveforms included as standard?
Not necessarily. The available waveforms depend on the selected model and project scope. Please specify your required waveforms before requesting a quotation.
Q4: Can the system test different types of electrical equipment?
Yes, when the voltage rating, energy, waveform characteristics, connections, and measurement arrangement are suitable for each test object.
Q5: How do we confirm the correct configuration?
Provide the required waveforms, voltage levels, equipment types, applicable standards, and any specific waveform tolerances stated in your test specification.
