Abstract

In the paper the comparative analysis of voltage harmonics measurements performed in the transmission network of 400 kV is presented. The voltage was measured using three measuring instruments: resistive voltage divider, inductive voltage transformer and capacitive voltage transformer. Measurement errors were estimated for transformers with reference to the harmonic values obtained with the use of the voltage divider.
