Product Description

The Professional Lightning Impulse Generator and Complete High Voltage Impulse Test System is a complete engineering solution for manufacturers and laboratories that need to establish or upgrade high-voltage impulse testing capability.

Rather than supplying only a generator, the complete solution can cover impulse generation, charging, waveform shaping, measurement, control, protection, grounding and laboratory integration.

Complete Testing Capability

Lightning Impulse

Standard 1.2/50 μs lightning impulse testing.

Switching Impulse

Longer-duration switching impulse testing for applicable high-voltage equipment.

Chopped Impulse

Chopped wave testing for evaluating insulation behavior under steep transient voltage conditions.

Waveform Measurement

Digital measuring systems can capture and analyze:

• Peak voltage
• Front time
• Tail time
• Waveform oscillation
• Chopping characteristics
• Test sequence
• Test results

Complete Application Range

The system can be used for:

• Power Transformer
• Distribution Transformer
• GIS
• Switchgear
• Circuit Breaker
• HV Cable
• EHV Cable
• Bushing
• Insulator
• Surge Arrester
• CT/PT
• Other HV Electrical Equipment

Customer Pain Points

1. “I don't know how to choose the right generator."

Send us:

Test voltage + test object + test standard + test object capacitance + required waveform

and the system configuration can be evaluated.

2. “I need a complete laboratory."

A complete project can include:

Impulse Generator → Charging System → Wave Shaping → Test Object → Voltage Divider → Digital Measurement → Control System → Safety System

3. “I need a quotation quickly."

For an initial quotation, the following information is especially useful:

• Required impulse voltage
• Impulse energy
• Test object
• Rated voltage of test object
• Test standard
• Required waveform
• Laboratory dimensions
• Country/project location
• Required delivery time

4. “I am worried about after-sales service."

For large HV impulse systems, customers should evaluate not only equipment price but also:

• Technical design
• Factory testing
• Installation
• Commissioning
• Operator training
• Calibration
• Spare parts
• Remote technical support
• Warranty
• Long-term maintenance

FAQ

Q: What is the difference between a Lightning Impulse Generator and an Impulse Voltage Test System?

A: A Lightning Impulse Generator is the core equipment used to generate the impulse. An Impulse Voltage Test System normally refers to the complete testing platform, including the generator, charging system, wave shaping, measurement, control and safety components.

Q: What is the difference between Lightning Impulse and Switching Impulse?

A: Lightning impulse represents a much faster transient waveform, commonly represented by 1.2/50 μs, while switching impulse has a much longer time scale and is used for applicable high-voltage equipment testing.

Q: What is a chopped wave test?

A: A chopped impulse is an impulse waveform intentionally interrupted at a specified point, allowing evaluation of insulation under a steep transient condition.

Q: What determines the price of a lightning impulse generator?

A: Major factors include:

• Maximum test voltage
• Impulse energy
• Number of generator stages
• Test object capacitance
• Waveform requirements
• Voltage divider
• Digital measuring system
• Automation level
• Safety system
• Laboratory integration
• Installation and commissioning requirements

Q: Can you design a complete transformer impulse test system?

A: Yes. A complete solution can be designed according to transformer parameters, required impulse test voltage, applicable standards, laboratory conditions and customer testing procedures.

Q: What information should I send for a technical proposal?

A: The fastest way is to send:

Test Object + Rated Voltage + Required Test Voltage + Required Energy + Test Standard + Laboratory Size

The engineering team can then evaluate the appropriate configuration.
