Have you ever been amazed by the immense energy instantly released by lightning? In the electric power system, to simulate and study the transient high voltage generated by lightning, we rely heavily on a crucial device - the lightning impulse high voltage generator. It serves not only as the "guardian" of safety performance testing for electric power equipment, but also as the "unsung hero" ensuring the stable operation of the power grid.

What is a lightning impulse high-voltage generator?

In simple terms, a lightning impulse high-voltage generator is a large-scale testing equipment capable of generating simulated lightning transient overvoltages. Its core task is to simulate the instantaneous high-voltage impulses that lightning may cause to power equipment (such as transformers, circuit breakers, insulators, etc.), thereby evaluating the withstand capability and insulation level of these devices in real lightning strike environments. This is like giving electrical products a "lightning strike resistance" physical examination.

Key factors affecting its performance

To obtain a stable and accurate impulse voltage waveform, many factors need to be considered:

Control of waveform parameters: The simulated lightning waveform, including surge amplitude, rise time, half-peak time, etc., requires precise control. This directly impacts the validity of the test results.

Energy storage and release: The generator needs to store sufficient energy and release it in a specific manner within a short period of time. The capacity of the capacitor bank and the control system for charging and discharging are key factors.

Insulation design: To generate and transmit such high voltage, the insulation design of the equipment itself is crucial, as it needs to prevent insulation breakdown.

Trigger accuracy: Accurate control of the generation time of impulse voltage is crucial for synchronous testing and data acquisition.
