Question { HZL, 19065 }

what is the meaning of transformer short circuit test?

Answer

IN THE SHORT CIRCUIT TEST WE DETERMINE THE COPPER LOSS .IN WHICH SECONDARY SIDE OF THE TRANSFORMER(LOW SIDE OF THE TRANSFORMER ) IS SHORT CKT BY THE AMMETER AND RELAY AFTER THAT WE APPLY RATED CURRENT ON THE HV SIDE OF THE TRANSFORMER AND HV SIDE A SMALL VOLTAGE ARE APPLY WHICH IS 2 TO 10% OF THE RATED VOLTAGE .SO THE VALUE OF THE VOLTAGE IS VERY LOW AS COMPARE TO THE FULL LOADED VOLTAGE .SO READING OF THE WATTMETER ARE ONLY THE READ THE VALUE OF THE COPPER LOSSES AND ALSO DETERMINE THE SHORT CKT PARAMETER Rsc , ZsC AND ALSO Xsc

Question { HZL, 19065 }

what is the meaning of transformer short circuit test?

Answer

ACTUALLY WE DETERMINE THE COPPER LOSSES BECAUSE COPPER LOSSES ARE BASICALLY EFFECTED TO THE EFFICIENCY
THE VALUE OF THE CURRENT IS VARIED ACCORDING THE LOAD SO THAT MINS BUT IN CASE OF THE TRANSFORMER THE both losses are not depend on the phase angle
