PURPOSE: A method exchanging a transformer in uninterruptible power supply is provided to exchange a transformer in low costs by including a low voltage bypass cable and a jump cable. CONSTITUTION: In a method exchanging a transformer in uninterruptible power supply, a support bracket(300) is installed in the electric pole of an A transformer and B transformer respectively. A low voltage by-pass cable(310) is installed in both support brackets. The both ends of the low voltage by pass cable is connected in parallel with the low voltage cable of each transformer The COS is of a first drop line of an A transformer is opened. A second drop line of the A transformer is removed. The A transformer is replaced. The second drop line of the A transformer is connected to the low voltage line. The COS of the first drop line is inputted. The support bracket and the low by-pass cable are removed. .
