Factory assemblies in substation design

DESIGNS and factory procedure for factory assemblies of medium voltage substations which may be applied to either network or radial distribution systems are described in this paper. These substations may be divided roughly into 2 principal classes, those for serving large individual power consumers and those for general distribution to a community of varied customers. In the latter class may be included also substations in very large industrial plants and steel mills having their own generating and transmission systems.
