Customized Lightning Impulse Generator for Insulators, Bushings and GIS High Voltage Insulation Withstand Test Equipment for Electrical Equipment Manufacturers

The Customized Lightning Impulse Generator is designed for electrical equipment manufacturers and laboratories that need impulse testing equipment matched to specific insulation test requirements.

Insulators, bushings, gas-insulated switchgear, instrument transformers, and high-voltage switching equipment have different electrical characteristics and testing requirements. A suitable impulse test system must therefore be selected according to the test voltage, waveform, test object capacitance, connection arrangement, and applicable standard.

Our engineering team can help evaluate these requirements and develop a system configuration covering impulse generation, voltage measurement, waveform recording, control, and safety interfaces.

• Application-specific voltage and energy configuration.
• Standard lightning impulse waveform support.
• Optional chopped-wave functionality.
• Compatible voltage measurement and recording.
• Customized connection and interface arrangements.
• Control and safety configuration based on the test environment.
• Engineering support for equipment manufacturers and testing laboratories.

Evaluates the insulation performance of compatible insulators under specified impulse voltage conditions.

Supports impulse withstand testing of bushings according to the applicable test specification and equipment rating.

Can be configured for appropriate impulse voltage testing of selected GIS components, circuit breakers, and other high-voltage apparatus.

Supports specified impulse testing requirements for compatible current and voltage transformers.

Provides an impulse voltage source and suitable measurement arrangement for laboratory insulation research.

1. Step 1: Understand your test objects
   Identify the equipment type, voltage class, insulation level, dimensions, and electrical characteristics relevant to the test.
2. Step 2: Confirm required waveforms
   Determine whether full-wave lightning impulses, chopped waves, switching impulses, or other specified waveforms are required.
3. Step 3: Define measurement requirements
   Select the measuring divider, digital recorder, and waveform analysis functions appropriate to the test.
4. Step 4: Review the laboratory environment
   Consider available space, electrical clearances, grounding, control room requirements, and access restrictions.
5. Step 5: Prepare the technical proposal
   Define the equipment configuration, included accessories, technical interfaces, installation scope, and commercial terms.

Q1: Can one generator be used for different test objects?

Potentially, if the selected system has suitable ratings and waveform capability and the correct test connections and procedures are used for each object.

Q2: Do we need to provide drawings of our equipment?

Drawings and electrical data are helpful, particularly for customized connections, layout planning, and complex test objects.

Q3: Can the system be designed for a specific national or international standard?

Yes. Please identify the applicable standard and edition. The proposed configuration and compliance scope can then be reviewed against the relevant requirements.

Q4: Can you supply a turnkey laboratory solution?

A broader project scope can be discussed, including generator, measuring system, control equipment, accessories, layout support, and agreed commissioning services.

Q5: What if our test requirements are not fully defined?

Provide the equipment type, rated voltage, intended tests, and any available specifications. Our engineers can help identify the missing information required for configuration.

Send your equipment specifications, required impulse voltage, and laboratory requirements. We can help develop an impulse testing solution suited to your application rather than offering a generic configuration.
