Lightning Impulse Generator for High Voltage Testing – High Voltage Lightning Impulse Voltage Test System for Transformer, Insulator, Cable and Switchgear
Product Description
The Lightning Impulse Generator is a high-voltage impulse testing system designed to simulate lightning overvoltage conditions and evaluate the insulation performance of high-voltage electrical equipment.
The system generates standardized lightning impulse voltages for laboratory, factory and research applications. It is widely used for testing power transformers, instrument transformers, bushings, insulators, switchgear, cables, GIS, surge protection equipment and other high-voltage components.
A typical lightning impulse waveform is 1.2/50 μs, which is widely used for insulation withstand testing. The system can also be configured for chopped lightning impulse and switching impulse tests according to specific test requirements and applicable standards.
The complete solution can integrate the impulse generator, charging system, wave-shaping circuit, chopping device, high-voltage divider, measurement system, control system and data analysis software, providing a complete solution rather than only a standalone impulse generator.
