AbstractNumerical overcurrent Relay is a type of protective relay that operates when a pre-set value exceeds a charge current. Because of its standard technology, numerical relay is better known as present generation relay. Overcurrent relay protects power systems in any aspect of the power network , i.e. transmission lines, transformers, generators or motors, against excessive currents. A relay program that is over-current is coded using the MPLAB platform. With the help of MATLAB Simulation the overcurrent is achieved. By varying the source voltage and the load resistance, we can find the usual load current values (In rms) and automatically increase the load circuit value when the short circuit element is inserted in that model that is being viewed as being overcurrent. Overcurrent data is trained in Artificial Intelligence (Neural Network) and implemented through coding in the NRDE Board. In NRDE testing software, a trip command is observed when overcurrent condition is reached.
