Abstract

A filter network is insertable into a power transmission line, to handle disturbances in the power transmission line. A first circuit has an RC network in parallel with a surge arrestor, to bypass high frequency disturbances of the power transmission line. A second circuit has inductors for carrying low-frequency power to and from impedance injection units.
