The paper considers the possibility of direct error correction when determining the position of the control switch from the primary and secondary voltages of individual transformers that have a larger number of recorded measured values of voltage and current in a smaller or larger load range. The direct correction builds on the previously performed error correction from the voltage drop on the transformer impedance, which is used to calculate the position of the control switch using voltage. Direct correction is performed by determining the mean value of all points and then subtracting the determined mean value from the value of individual points.
