Answer / vshnu

that is l.v side,
at h.v side current is less and voltage is high
but l.v side voltage is less and currents is high
in order to get current rated we have to short circuit the l.v terminals by applying less than rated voltage at h.v side.
the small amount of voltage at h.v side is enough to produce rated current at l.v side so that test is conducted on l.v side only,
the small amount of voltage at l.v side not able to produce
rated current at h.v so we are not short circuiting h.v side
