High Voltage Lightning Impulse Generator and Impulse Voltage Test System for

The High Voltage Lightning Impulse Generator and Impulse Voltage Test System is a professional high-voltage testing solution designed to generate controlled impulse voltages for evaluating the insulation withstand capability of high-voltage electrical equipment.

The system is widely used for power transformer, distribution transformer, GIS, switchgear, high-voltage cable, bushing, insulator, surge arrester and other electrical equipment testing.

It can be engineered according to the required test voltage, impulse energy, test object, waveform requirements and applicable international standards.

The complete system can integrate the impulse generator, charging unit, wave-shaping network, chopping unit, high-voltage divider, digital measuring system, control system and safety protection system.

Industry products commonly position impulse voltage systems around lightning impulse, switching impulse and chopped impulse testing for transformers, cables, GIS and arresters.

Impulse testing can be applied to high-voltage cable systems according to applicable testing standards.

“We don't know what voltage and energy rating we need."

The generator should not be selected based on voltage alone. The required test voltage, test object capacitance, impulse energy, waveform requirements and applicable standard should be considered together.

“We need a complete system, not only a generator."

A complete solution can include the generator, charging system, wave-shaping components, divider, measuring system, control system and safety interlocks.

“We need reliable waveform measurement."

The measuring system is critical because the customer needs to verify not only the peak impulse voltage but also the waveform parameters.
