Inductive Voltage Transformer Behaviour in the Frequency Range from 9 kHz up to 150 kHz

The study investigates the impact of high-frequency distortions (HFD) on power quality, focusing on the behavior of inductive voltage transformers (VT) within the frequency range of 9 kHz to 150 kHz. Results indicate that the non-linearity of the iron core affects the performance of VTs, highlighting the need for accurate measurements to address distortion challenges. The project is funded by the European Union to enhance measurement standards.

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.
