Overview
The ability to accurately and reliably classify the different types of fault, so that single pole tripping and autoreclosing can be used plays an important role in today’s power systems. “Phase selection, quadrilateral characteristic with settable angle (FRPSPDIS)” is designed to accurately select the proper fault loop in the distance function dependent on the fault type.
