Effect of line length on the fault current due to line to ground fault in transmission line using MATLAB Simulink

Abstract

Today, electrical power is a necessity for many aspects of daily living, including works in homes, businesses, industries, and agriculture. This article is created to ensure that the electrical power needed by these sectors is maintained. In an electrical system, numerous faults can arise owing to line-to-ground (L-G), line-to-line (L-L), and three lines (L-L-L). This study addresses the analysis of fault current under line-to-ground (L-G) and how it varies with the fault position. MATLAB Simulink has been utilized in this work to demonstrate how fault current depends on the line length of transmission system during L-G faults.
