Abstract

It is useful to understand the frequency response of voltage transformers used for power quality monitoring, so that power quality data is captured accurately and can be used for compliance purposes. This paper reports the results of frequency response testing conducted for Western Power Distribution at The University of Manchester of four 1-phase and 3-phase voltage transformers of types used in 11 kV and 33 kV distribution networks in Great Britain. The results show that the tested voltage transformers transfer harmonic voltages with attenuation that increases with frequency, and suggests that correction factors may be required to obtain accurate results at harmonic frequencies up to at least the 50th harmonic order.
