What is the leakage current standard

Safety leakage current of electrical appliances is 30mA.Leakage current is actually the electrical line or equipment in the absence of faults and the role of the applied voltage, the current flowing through the insulated part. Therefore, it is one of the important signs to measure the insulation of electrical appliances, is the main indicator of product safety performance. Leakage current will be limited to a very small value, which is to improve product safety performance has an important role.

What are the precautions for leakage current measurement

1, leakage current measurement is charged for measurement, the measured appliance shell is charged. Therefore, the test personnel must pay attention to safety, a variety of laboratories should develop safe operating procedures, in the absence of cutting off the current before, shall not touch the measured appliances;

2, in the working temperature measurement of leakage current, if the measured appliances are not powered by the isolation transformer, the measured appliances should be colored insulation properties of reliable material insulating pads insulated from the ground. Otherwise there will be part of the leakage current flows directly through the ground without passing through the instrument, affecting the accuracy of the test data;

3, should try to minimize the impact of the environment on the test data, the test environment of the temperature, humidity and pollution of the insulating surface, for the leakage current has a great impact on the temperature is high, high humidity, the insulating surface of the insulation is seriously contaminated, the determination of the leakage current value is larger.
