Abstract

The growing need of power quality analysis in medium voltage grids leads to the employment of transducers with wider and wider bandwidth. This requirement is in contrast with the need of adopting a low cost hardware for capillary monitoring. Therefore, in this paper a technique for the extension of the frequency bandwidth of MV voltage dividers is presented. The performance of the compensated dividers is comparable with that of dividers of better accuracy class, but the cost is kept low.
