Directional overcurrent protection provides a significant degree of security to protect feeders especially in case of double ended fed systems and parallel feeders in ring formation. Because of its importance, it is widely used on both transmission and distribution levels of our power network. Every personnel working with system protection under his/her belt should know the fundamentals behind its implementation.
This webinar will provide some refresher on the theory and explain traditional methods to determine directionality back in the electromechanical relay days and also what we have now in the microprocessor world. It will also provide users an insight on how to test those elements on both electromechanical and micro-processor relays.
