What is principal to reduce earth leakage current with isolation transformer? When isolation transformer is installed in input stage of system, earth leakage current is reduced. the reason is why the leakage current of 2nd stage of isolation transformer does not affect the 1st stage's leakage current. I would like to know the reason. As you know, earth leakage current is a kind of AC. So, How to reduce earth leakage current in case that isolation transformer is used?
