Earth Fault Indicator Circuit have some problems

Hello,

In "Earth fault indicator" circuit the green LED lights on even when a bad earth connects to earth input.

I have connected an earth with a very high resistance to circuit and the green LED turned on.

It lits on even when I touch the earth connection with my hand with plastic shoes.

What do you think of this?

Regards,

M.R.Mahdavifar
