Abstract

A deviation compensation method of a potential transformer is provided. The deviation compensation method includes: detecting an output voltage value of a first potential transformer; checking a compensation value applied to the first potential transformer; compensating for the output voltage value based on the compensation value to measure an actual voltage value for a location at which the first potential transformer is installed; verifying the validity of the measured actual voltage value; and resetting a deviation compensator measuring the actual voltage value according to a result of verification on the validity of the actual voltage value.
