When testing, a leakage current tester is used, mainly testing its L pole and N pole. The principle of measuring leakage current is basically the same as that of measuring insulation resistance. Measuring insulation resistance is actually a kind of leakage current, but it is expressed in the form of resistance. However, a regular measurement of leakage current applies an alternating voltage, and the component of the leakage current includes capacitive component current. Therefore, it is necessary to set up an on-line monitoring device for high-voltage leakage current.

When the conversion switch K is connected to the zero line, the leakage current sampled by the tester is the leakage current between the neutral line and the outer shell; when K is connected to the phase line, the leakage current between the phase line and the outer shell is tested. It should be noted that: whether K is connected to the zero line or K is connected to the phase line, the leakage current may not be the same.
