The impulse voltage generators type H are the main components of impulse voltage test systems, consists two impulse capacitors for each stage, ranging from **0kV to ***0kV cumulative charging voltage.
Â
Impulse voltage test systems are used for impulse voltage testing of transformers, cables, gas-insulated switchgears (GIS), insulators, arresters, and other high-voltage devices. The test systems generate lightning impulse voltage (LI, 1.2/*0 μs), chopping lightning impulse voltages (LIC, front time 1.2 μs, front, crest or tail chopped), and switching impulse voltage (SI, **0/***0 μs) in accordance with IEC ******1; as well as IEC ******3 for transformers, and IEC ****7, ****0 and ******1 for cables), etc. Also it can be used for steeping and oscillating impulse test by adding some extra equipment.
Â
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).
Â
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 **0kV 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.
