ABSTRACT:
This invention relates to a current transformer support assembly for use in an electromotive machine that includes an armature slideably secured to the electromotive machine housing. The armature end windings have radially disposed neutral armature conductors. The support assembly includes an arcuate shaped support member secured internally of the housing within a recessed region of the housing. The arcuate shaped support member is provided with at least one well shaped opening in which a secondary current transformer winding is positioned. A neutral armature assembly is provided that includes an arcuate strap secured in a mating manner to the support member. The neutral armature assembly has a neutral lead which acts as a primary for the current transformer. The neutral lead is secured to the strap and passes through a central opening in the current transformer winding for electrical connection to a neutral armature winding. The current transformers so mounted are completely supported by the housing.
