This HV impulse test system mainly consists of impulse voltage generator, charging device, damped capacitive divider, automatic control and measure system, chopping sphere gap, and other optional components (supporting resistors, glaninger circuit, etc).
The circuit of impulse generator is the Marx multiplier circuit. Impulse capacitors arranged in the stages of the generator are charged in parallel with DC voltage up to 100kV against earth potential and, in order to generate impulses, connected in series by spark gaps. For adjustment of front time and time to half value of the test impulse, the generator stages comprise front wave resistors and tail wave resistors. A short discharge loop guarantees low internal inductances and smooth voltage shape.
Number of Stages：1-12 Stages
