i dont think circulating current will flow through earthing,
since the voltage is lesser.It can only heatup core and
insulation.
Core earthing doing for the purpose of operator
protection.incase of any insulation leakage or damage, the
operator will get shock hazard.This can be saved by earthing.
More over the this will ensure the ELR to opearte in case
any earth leakage from transformer.
