1200kV High Voltage Lightning Impulse Generator, 120kJ Impulse Voltage Test System for Transformer, GIS, Switchgear and High Voltage Equipment Testing

The 1200kV High Voltage Lightning Impulse Generator is a large-capacity impulse voltage test system designed for high-voltage laboratories, transformer manufacturers and electrical equipment testing facilities.

The system can be configured with high-energy impulse generation, charging, wave shaping, high-voltage measurement and computer control.

The actual voltage and energy configuration should be selected according to the customer's test object and required test level rather than simply choosing the largest available rating.

Commercial high-voltage impulse systems are commonly offered from hundreds of kV to several MV, with modular multi-stage configurations and project-specific energy ratings.

Customers frequently ask:

“I need a 1200 kV generator. What is the price?"

For engineering quotation, additional information is important:

• Required test voltage
• Impulse energy
• Test object capacitance
• Required waveform
• Number of stages
• Charging voltage
• Measurement accuracy
• Laboratory size
• Test standard

For a complete laboratory, the customer may need:

Impulse Generator + Charging System + Wave-Shaping Network + Voltage Divider + Digital Oscilloscope/Impulse Analyzer + Control System + Safety System

Q: Can you quote a 1200 kV/120 kJ system?

A: Yes, but the final configuration should be confirmed according to the test object, waveform and applicable testing requirements.

Q: Is 120 kJ the same as 120 kV?

A: No. kV represents voltage, while kJ represents stored/impulse energy. Both parameters are important when selecting a high-energy impulse generator.

Q: Can the system be used for transformer testing?

A: Yes. Transformer impulse testing is one of the major applications.
