[0002] Leakage is the leakage of current caused by insulation damage or other reasons. When the housing of an electrical appliance is connected to the live wire of the mains for some reason and there is a certain potential difference between the electrical appliance and the ground, leakage will occur. The best way to detect leakage is to touch the charged object with a test pen. If the neon bulb lights up and then goes out immediately, it proves that the charged object is carrying static electricity. If it stays on for a long time, it is definitely leakage.
