ABSTRACT:
A high-voltage filter for filtering of harmonics in an electric power network comprises a first capacitive impedance element (C.sub.1) arranged in a first electric circuit (L.sub.1, C.sub.1) and a second (C.sub.2) capacitive impedance element arranged in a second electric circuit (L.sub.2, C.sub.2). The first and second electric circuits are inductively coupled to each other.
