An impulse voltage generator is a high-voltage device used to generate lightning or operational shocks. The impulse voltage generator is mainly used for conducting impulse voltage tests on power equipment and other test objects, including full wave lightning impulse voltage, cut-off lightning impulse voltage, and operating impulse voltage, to test insulation performance. The impulse voltage generator uses multi-stage capacitors for parallel charging and series discharging to generate the required voltage. Its waveform can be adjusted by changing the resistance values of Rf and Rt, the amplitude can be adjusted by the charging voltage V, and the polarity can be changed by reversing the two poles of the silicon stack D.
An impulse current generator is a device used to generate impulse currents. The surge current generator is mainly used to test the ability of electrical equipment to withstand surge current stability. It is widely used in surge current tests on zinc oxide lightning arrester valve plates and can also be used in other research tests.
