The aim of this study is to discuss the challenges that will be faced by the designers of measuring instruments in future, in the wake of the proliferation of microgrids. In this context, the fluctuations in the angular frequency of the fundamental component of the voltage and the resulting changes in the duration of the measurement windows are considered. The main objective of this study is to consider this variation in the angular frequency from the point of view of the IEC Standard 61000-4-7, using real signals. Numerous results from the experiments conducted in 11 electric power networks, chiefly marine microgrids, are presented, and discussed. A comparative analysis of the behaviour of two measuring instruments is also provided. Both the instruments are based on different signal processing principles. One of them utilises the signal processing method recommended in the IEC 61000-4-7 standard, whereas, the other is based on the application of the chirp z-transform principle.
