    Abstract

    This paper presents the results of several sweep frequency response analysis (SFRA) measurements performed on two identical offshore wind farm transformers. A comparison is made between the transformers based on different recommended measurements and procedures, different measurement systems for frequency response analysis (FRA) and different tap changer positions. It was shown how the series impedance and capacitance between windings vary depending on the tap changer position.
