WebSep 8, 2024 · In this tutorial, the theoretical foundation of overcurrent relay is formulated and it will be designed in MATLAB/Simulink. Overcurrent time protection is a selective type of overload and short-circuit protection used mainly in radial networks with single-ended feed as found in medium-voltage systems. A radial network is shown in the figure below.
