Abstract
A deviation compensation method of a potential transformer is provided. The deviation compensation method includes: providing first to Nth potential transformers to be installed at different locations in a high voltage direct current (HVDC) transmission system; supplying a first voltage to the first to Nth potential transformers provided; measuring voltage values output through the first to Nth transformers by the first voltage supplied; determining whether there is a deviation between the measured voltage values; and determining compensation values for correcting the measured voltage values to the same voltage value when there is the deviation.

A deviation compensation method of a potential transformer, the deviation compensation method comprising:
- supplying, by an integrated measurement panel, a first voltage to first to Nth potential transformers, wherein the first voltage is a voltage for measuring a voltage output from each of the first to Nth potential transformers;
- measuring, by the integrated measurement panel, the voltage output from each of the first to Nth potential transformers;
- determining, by the integrated measurement panel, for each of the first to Nth potential transformers, whether a deviation of the voltage output exists between any of the first to Nth potential transformers;
- when the deviation of the voltage output exists between any of the first to Nth potential transformers, determining, by the integrated measurement panel, for each of the first to Nth potential transformers, a compensation value which is used to make same the voltage output from each of the first to Nth potential transformers, and
- when any of the first to Nth potential transformers on which compensation values have been determined has a fault that requires replacement of such potential transformer having the fault with a new potential transformer, determining, by the integrated measurement panel, a new compensation value for the new potential transformer based on the determined compensation value of each of the first to Nth potential transformers.
