Current sensor assembly

A current sensor assembly comprising:

• a first housing assembly and a second housing assembly configured to each surround a portion of a conductor;
• and
• a first winding assembly movably disposed in said first housing assembly, and a second winding assembly movably disposed in said second housing assembly;
• wherein said first housing assembly and said second housing assembly are transitional between an opening position and a closed position, and
• wherein said first winding assembly and said second winding assembly are movable with respect to said first housing assembly and said second housing assembly, respectively, to align said first winding assembly with said second winding assembly, and
• wherein at least one of said first housing assembly or said second housing assembly, or combinations thereof, comprises a current sensor electronic device configured to process a measured power parameter, wherein said current sensor electronic device includes compensation circuitry configured to actively compensate for ratio and phase errors.

The current sensor assembly comprising:

• a first housing assembly and a second housing assembly configured to each surround a portion of a conductor;
• a first winding assembly movably disposed in said first housing assembly, and a second winding assembly movably disposed in said second housing assembly;
• wherein said first housing assembly and said second housing assembly are operative to be transitional between an open position and a closed position, and wherein said first winding assembly and said second winding assembly are movable with respect to said first housing assembly and said second housing assembly, respectively, to align said first winding assembly with said second winding assembly;
• and
• an elastic component disposed between at least one of said first housing assembly and said first winding assembly or between said second housing assembly and said second winding assembly, wherein said elastic component is operative to apply a force to said first winding assembly or said second winding assembly to contiguously align a contact surface included on each of said first winding assembly and said second winding assembly when said first housing assembly and said second housing assembly are in said closed position.

A sensor apparatus mountable on a power conductor, the sensor apparatus comprising:

• a current sensor assembly operative to sense current in a power conductor;
• an electronics assembly included within said current sensor assembly;
• wherein said current sensor assembly further comprises a housing with a main winding, a compensation winding, a plurality of transformer cores, and a carrier disposed therein,
• wherein said carrier is operative to support said transformer cores in parallel in at least one dimension, and is operative to be moveable with respect to said housing,
• wherein said compensation winding encircles at least one of said transformer cores without encircling said carrier, and said main winding encircles said compensation winding and said current transformer cores;
• and
• wherein said electronics assembly comprises a communication circuit and a power supply operative to supply power to said current sensor assembly.
