摘要：

With the widespread diffusion of power converters able to be directly connected to Medium Voltage (MV) grids, there is the need to measure high frequency distortion, that is from 9 kHz up to 150 kHz. Inductive Voltage Transformers (VTs) are still the most installed voltage transducers in the power systems, but the knowledge of their behaviour in this frequency range is still an open issue. The aim of this paper is to analyse the behaviour of inductive VTs from 9 kHz up to 150 kHz. A commercial VT has been tested and the results show that the nonlinearity of the iron core can influence the behaviour of inductive VTs at least up to 150 kHz.
