| Zusammenfassung: | The present application is directed to a three phase power transmission system including a first conductor line, a second conductor line and a third conductor line. One or more sensors are configured to detect traveling waves in each of the first second and third conductors. A controller is configured to receive data transmitted by the one or more sensors and determine which of the traveling modal waves is a first metallic mode wave (MM1), a second metallic mode (MM2) wave and/or a ground mode (GM0) wave. The controller is operable to determine which of the conductor lines are faulted based on detection of one or more of MM1 waves, MM2 waves and/or GM0 waves. |
