Patent ID: 8896290

Claim:
A current sensor comprising: 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 completely encapsulate the closed core and the at least one conductor that connects the input terminal and the output terminal, wherein the gap, the input terminal and the output terminal are not encapsulated by the molded case, wherein the molded case is dimensioned such that internal and external spacings defined by the molded case are suitable for continuous operation with an AC voltage between the range of 1,000 volts and 69,000 volts as applied to the input terminal, the output terminal and the at least one conductor while the core is at ground potential.
