Converting 2.3-kv feeders to 4-kv operation: Outlining a successful method of procedure

Although the question of the relative merits of converting 2,300-volt distribution feeders to 4,000-volt operation has been treated liberally in technical literature, relatively little has been published concerning efficient methods of accomplishing such conversions once they have been decided upon for economic or other reasons. Hence the accompanying outline of a successful procedure is presented in the hope that it may be of interest and value to many engineers faced with some of the problems involved. The authors are in effect presenting the accumulative results of three years of actual field work incident to the conversion of some 45 distribution feeders.
