FIVESTAR HV TESTING EQUIPMENT, operating in the electricity industry, specializes in developing and providing high-voltage testing equipment, including AC Dielectric, HV DC Voltage, Impulse Voltage, Impulse current and other special tests. We offer comprehensive solutions for research, manufacturing, or maintenance purposes.
Model：FIVG-M2
Voltage Range：400-5000kV
Charging Voltage：100/150/200kV
Modular type systems are 400kV or 600kV in one module, easy to be installed on field.
Test system mainly consists of impulse voltage generator, charging device, damped capacitive divider, automatic control and measure system, and other components.
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.
