Introduction was made to a method improving the output waveform of lightning impulse voltage test for large capacitive loads. This paper analyzed the reason of lightning impulse voltage waveform oscillation and overshoot under capacitive load. The common mea-sures were used to debug lightning impulse voltage waveform and the existing low-pass iflter circuit was improved by the way of series RLC iflter circuit in impulse voltage test circuit. The simulation result shows that the waveform of the improved RLC low-pass iflter circuit is smoother than the waveform of the original circuit. The lightning impulse voltage waveform oscillation has been improved obviously.
