Application of adaptive reclosers to automatic distribution systems

This paper presents a discussion on several issues related to adaptive reclosers. It is shown, by using a realistic example, that adaptive reclosers should be installed in distribution systems with automatic switching capabilities in order to optimize their protective function. In particular, the case of primary circuits with automatic transfer systems is discussed. The conclusion is that the fuse-saving scheme normally implemented in primary-radial distribution systems can be automatically achieved for the different configurations of the primary circuit when adaptive reclosers are used. The paper also presents a brief discussion on the requirements that should be met by application programs for adaptive distribution protection.
