Product Introduction
Der Lightning Impulse Test System is a device used to simulate lightning strikes, which can generate high voltage and high current for electrical performance testing and safety evaluation of electrical equipment.
The Lightning Impulse Test System uses electromagnetic induction principle to generate high voltage and high current through high-voltage power supply and discharge device, simulating lightning impulse. The discharge device usually includes an energy storage capacitor and a discharge wire. After the capacitor is charged, the discharge wire releases lightning energy into the tested equipment, generating instantaneous high voltage and high current.

Frequently Asked Questions
Q: What equipment is the lightning impulse high-voltage generator mainly used for testing?
A: Mainly used for various high-voltage power equipment such as transformers, circuit breakers, transformers, insulators, cables, GIS (gas insulated switchgear), etc.
Q: Why is it necessary to simulate lightning strikes? Isn't a real lightning strike enough?
A: Real lightning strikes are random and uncontrollable, and cannot be used for systematic equipment testing and safety assessment. Simulators can precisely control testing conditions, ensuring the reproducibility and comparability of results.
Q: What are the standards for generating lightning impulse waveforms?
A: There are various international and domestic standards, the most common of which include 1.2/50 μ s (standard lightning impulse voltage) and 250/2500 μ s (operating impulse voltage), as well as some special short-term impulse voltages.
Q: What is the difference between lightning impulse high-voltage generator and ordinary high-voltage testing equipment?
A: Ordinary high-voltage testing equipment (such as power frequency withstand voltage testing devices) mainly tests the insulation ability of the equipment under long-term stable high voltage, while lightning impulse high-voltage generators focus on transient and ultra high voltage impulses that occur in a very short period of time.
Q: How to choose a suitable lightning impulse high-voltage generator?
A: The selection needs to be based on the voltage level of the device under test, the required amplitude and waveform of the impulse voltage, and the overall requirements of the high-voltage test. Wuhan UHV Power Technology Co., Ltd. can provide professional consulting and customized solutions.
