The impulse voltage generator is mainly used for conducting impulse voltage tests on power equipment and other test objects,including full wave,cut wave,operating impulse voltage,and steep wave lightning impulse voltage,to test insulation performance.

　　The 1200kV,2400kV,and 4800kV series impulse voltage generators can generate three types of impulse voltage waveforms:standard lightning full wave,operating wave,and lightning cut wave.

　　The 1200kV series impulse voltage generators can generate eight types of impulse voltage waveforms:standard lightning wave,operating wave,lightning cut wave,oscillating lightning wave,oscillating operating wave,line insulator steep wave,composite insulator steep wave,and transformer induced operating wave.
