ABSTRACT:
A combined current and voltage measuring sensor for measuring voltage and current on a primary conductor, the sensor including a cast resin body having therein a aluminum support, the support having an aluminum encasement mounted thereto. An air core coil is encapsulate with the encasement within the cast resin body adjacent a grooved portion in the cast resin body for maintaining the primary conductor in the top of the cast resin body. The groove and the aluminum encasement cooperate to precisely locate the primary conductor with respect to the air core coil. A keeper assembly mechanically maintains and locates the primary conductor in the groove and further provides an electrical connection from the primary conductor to the voltage measuring apparatus of the sensor. A corona shield encapsulated within the cast resin body is at the same potential as the conductor and is interposed between the air coil and the groove of the cast resin body.
