Research of Methods for Fault Location Determination Using Signals from Digital Current and Voltage Transformers

The high-voltage power lines are quite often the damaged parts of an energy system. The line outage is always accompanied by the undersupply of energy, decreased reliability, cost and quality of electric supply. That's why one of the important tasks of line maintenance is a quick location determination of the damage and organization of the rehabilitation. [1], [2]. There are wide-spreading methods and means of remote fault location on the power lines in power industry based on measurement of the emergency mode parameters (EMP). So, the main part of this paper includes the development and research of the methods and algorithms for fault location based on the one-sided measurement of EMP. This type of measurement uses the signals from digital current and voltage transformers as input ones [3]–[5].
