Abstract
This paper presents a method to correct for measurement error, which c an be introduced by current and voltage transformers, Motivated by the development of an accurate real-time power quality analyzer, a compen sation scheme was developed and implemented as a digital filter. An ex ample of the reduction of measurement error from the uncompensated to the compensated case is given, It is shown that the compensated system provides reduction by a factor of more than 1000 in the measurement e rror.
