Analytical Study of Quarter-Wave Filter Performance on Power Transmission Lines

A general analysis is applied to quarter-wave filters on single-, two-and three-phase power lines. Attenuations of 6dB and 9dB for bandwidths of about 12 and 7 percent have been found for single conductor lines. Performance of filters with resistive and capacitive terminations is discussed. It is concluded that this type of band-attenuation filters presents many attractive features of practical importance.
