Lightning Impulse Generator with Chopped-Wave and Switching Impulse Testing Multi-Waveform High Voltage Test System for Transformers, GIS, Bushings and Insulators

The Multi-Waveform Lightning Impulse Generator is designed for high-voltage testing laboratories that require more than one impulse waveform.

Depending on the selected configuration, the system can generate lightning impulse full waves, chopped waves, and switching impulse waveforms for specified insulation testing applications.

The equipment may include a multistage impulse generator, charging unit, wave-shaping network, chopping equipment, switching impulse components, high-voltage measuring divider, digital recorder, and control cabinet.

Available waveforms and output ratings should be confirmed against the actual test requirements before purchasing.

• Multiple impulse waveform configurations.

• Full-wave lightning impulse generation.

• Optional chopped-wave generation.

• Optional switching impulse generation.

• Waveform measurement and recording.

• Adjustable operating parameters within the system's design limits.

• Integrated control and safety functions.

• Customized configuration for different test objects.

Full-Wave Lightning Impulse: Generates the specified standard lightning impulse waveform.

Chopped-Wave Impulse: Uses a compatible chopping circuit to produce the required chopped waveform.

Switching Impulse: Supports specified switching impulse tests when the appropriate configuration is included.

Waveform Analysis: Records relevant waveform parameters for technical evaluation and test documentation.

• Power transformer testing

• GIS and switchgear testing

• High-voltage bushing testing

• Insulator and insulator-string testing

• High-voltage insulation research

• Electrical equipment type testing

Unclear configuration options: Confirm which waveforms are included as standard and which require additional components.

Concern about test compliance: Match the waveform parameters to the applicable test standard and equipment specification.

Need to test multiple product types: Evaluate whether the selected voltage rating, energy, and waveform configurations support each intended test object.

Need complete documentation: Ask for waveform measurement specifications, test records, and available data export functions.

Q1: What is the difference between a full-wave and chopped-wave impulse?

A full-wave impulse follows the specified impulse waveform. A chopped-wave impulse is intentionally interrupted at a defined point using an appropriate chopping arrangement.

Q2: Can the same generator perform switching impulse tests?

A suitably configured system can support switching impulse testing when the required components and measurement arrangements are included.

Q3: Are all waveforms included in the base price?

Not necessarily. Confirm the included waveform functions and accessories in the quotation.

Q4: Can the system test several kinds of electrical equipment?

Yes, where the ratings, waveform capabilities, connections, and measurement setup are suitable for each application.

Q5: How do we select the correct configuration?

Provide the test objects, voltage requirements, waveforms, applicable standards, and any specified waveform tolerances.
