The test procedure was repeated 1000 times with a capacitor charged with a dc voltage of several hundred volts and then discharged through a short-circuiting device as close to the capacitor as possible.
The traditional discharge method is that a customized pure copper tool bit is connected with one end of an electrode, the other end of the electrode is fixed with a copper plate, a rope is tied on the tool bit, and a tester pulls up the tool bit through pulling the rope. After the capacitor is charged, the rope is loosened to enable the cutter head to strike the other copper plate electrode, and therefore discharging is achieved.

Because the number of times of experiment is more, consume a large amount of manpowers, and relate to high tension electricity in the testing process, very dangerous. Therefore, the current experimental device is low in test efficiency, short in practical service life of the tool bit and has certain potential safety hazard.
