Earth leakage current Test according to (IEC 60601-1)

Posted on Updated on

What is leakage current :-  

High voltage is generated in an electrical appliance that use a chimerical power supply as its main power source. Should an abnormality occur in such an appliance(due to faulty design or fault), electric current flows through the body of anyone who touches the appliance. This electric current is called “ leakage current.”

Earth leakage current:-

The electric current that flow through a protective grounding wire to the ground is knows as earth leakage current.

Earth leakage current

Earth leakage current process

How to perform:-

For class I equipment, earth leakage current is measured as shown in figure 1. The earth leakage test is valid for class 1 equipment with Type B, BF and CF applied part.
According to IEC 60601-1 standard Earth Leakage Current (8.7.3 d) .  The allowable earth leakage current to 5mA in normal condition and 10mA under single fault condition.

Procedure:-

1. As shown in the figure 1 , Connect the instrument to the equipment under test with the power cord.
2. Start earth leakage current measurement.
