A New Technique for Location of Fault Location on Transmission Lines

Abstract

Magnetic field sensors can be used to detect fault detection and location effectively. Quick fault detection can help protect equipment by allowing the disconnection of faulted lines before any significant damage is done. A variety of algorithms continue to be developed to perform this task more accurately and more effectively. Particularly fault impedance (based algorithms) require both current and voltage information. However, it is possible to monitor a transmission system without using current or voltage transformers through the analysis of the magnetic field near the conductors. Since each conductor in a transmission line creates a magnetic field due to the current pass through it. Magnetic field sensors are used and tested using MATLAB through analyzing wave fault detection and location as there is a possibility of analyzing the transmission line system based on the resultant magnetic field produced. The results show that the magnetic field sensors are a viable tool for power transmission line fault detection, so this method is highly recommended to be used based on its efficient and accuracy.
