Answer / dp kothiyal

due to capacitance between ground - primary or ground-
secondary. for safety of human being as well as windings it
is grounded.

Answer / k.prakashchandra

To remove the influence of high voltage of primary in the
secondary due to capacitance between primary and secondary .

Answer / kvn

when it is open huge amount of voltage produced in secondary circuit of CT.which cause severe damage to power system equipments.To prevent this condition we usually shorted ct secondary.
