Method for locating a fault on a line near to a measuring location with the aid of substitute signals |
摘要 |
A method for locating a fault on a line wherein starting from a fault-free operating state of the line there is derived a substitute-measurement voltage signal which corresponds at least approximately to a frequency component of a line voltage both in magnitude and phase and is approximately independent of breakdown of the line voltage at least for a limited time interval. The substitute-measurement voltage signal is used to form at least one substitute-traveling wave signal and a substitute-evaluation signal.
