An Improved Automatic Circuit Recloser

Several years of field experience with automatic circuit reclosers indicated room for worth-while improvements in the existing design. This earlier recloser incorporated time-lag tripping characteristics to allow co-ordination with other reclosers and with fuse links. the imporoved design helps reduce outage time by extending the range of co-ordination with fuses by means of high speed tripping and reclosing. This paper describes the new recloser and points out the application of its new features.
