Abstract

The closed-loop distribution system is more flexible and more reliable than radial system. If any type fault occurs, the reliability of system can be better by providing electrical energy through another distribution line. However, it needs protection device coordination of different type. Typically, it is available by using directional overcurrent relay (67). This paper gives a solution about loop protection relay modeling which can be used by the simulation tools.
