PROBLEM TO BE SOLVED: To achieve a deviation compensation method for an instrument transformer which compensates the deviation of a voltage value measured by a plurality of instrument transformers.SOLUTION: A deviation compensation method for an instrument transformer includes: a step for preparing first through N-th instrument transformers installed at positions different from each other in an extra-high-voltage DC power transmission system; a step for supplying a first voltage to the first through N-th instrument transformers thus prepared; a step for measuring a voltage value outputted via the first through N-th instrument transformers by the first voltage thus supplied; a step for determining whether or not a deviation has occurred between the voltage values thus measured; and a step for determining a compensation value for compensating the voltages values thus measured to the same voltages value upon occurrence of a deviation. |
