Development of Remote Fault Location Method based on Synchronized Two-sided Measurement

Overhead high-voltage power lines are the longest and quite often damaged parts of an energy system. A line outage is always accompanied by the undersupply of energy, decreasing the reliability, cost and quality of electric supply. That is why one of the important tasks of line maintenance is a quick search for the location of damage and organization of the rehabilitation. The increase of the accuracy of automatic remote fault location (RFL) and development of new RFL methods including the methods of self-clearing fault location represent a current challenge. This article is devoted to the results of development and research of synchronized two-sided RFL method using signals from digital current and voltage transformers as input. The means of increasing its accuracy are considered.
