Abstract
A method is investigated for detecting the fault-induced high-frequency voltage signals of the EHV transmission lines for protection applications. The method is based on the principle of a power line carrier communication system using a stack tuner for detecting the high-frequency voltage signals in a particular frequency bandwidth. The digitally simulated fault responses of different frequency bandwidths in the kilohertz range and at different fault inception angles of the voltage waveform are studied
