A characterized method for the real-time compensation of power system measurement transducers

The paper analyses a real-time compensation method for the improvement of the frequency behavior of measurement transducers already operating or newly installed in transmission and distribution grids. After a brief description of the developed technique, which is based on the identification of a digital filter, attention is focused on the characterization of its performances. To this end, the method is applied to a low voltage divider, whose configuration and components are known. The algorithm capabilities are evaluated by comparing the identified filter inverse transfer function with the divider measured one.
