Abstract
A current sensor for measuring medium-voltage currents. The current sensor includes an input terminal configured to receive a current, an output terminal configured to transmit the current, a closed core made from a magnetic material and comprising a gap, at least one conductor operably connected to the input terminal and the output terminal and passing through the closed core, the at least one conductor sized to carry the current, and a molded case of solid dielectric material configured to encapsulate the closed core and the at least one conductor, wherein the gap and the terminals are not encapsulated by the molded case. The molded case is dimensioned such that internal and external spacings defined by the molded case are suitable for continuous operation with a medium voltage current as applied to the terminals and the at least one conductor while the core is at ground potential.
