side some earth current will flow in lv side thats will be
approximately 1-2A will flow

Answer / mrinmoyboruah

Cable insulation together with cable conductors form
capacitance. On nergising a cable this capacitance gets
charged and cable charging current flows even if no load is
connected at cable end. Similarly when cable is disconnected
from power source it retains the original charging energy
until it finds a conducting path to earth for discharge.
Hence before touching a disconnected cable all its
conductors including metal sheath and armours should be
connected to a earth path so that the stored energy in the
cable gets discharged.
