Current sensor arrangement
First Claim
1. A Rogowski coil for a current sensor arrangement comprising a split helical structure that defines a complete turn and a coil winding distributed over the split helical structure so as to encircle a conductor and such that the ends of the Rogowski coil are not coincident whereby the Rogowski coil may be positioned about a conductor.

Abstract
A current sensor is provided including a Rogowski coil in an assembly that is easily positioned about a conductor, e.g. without cutting the line or deenergizing the line. In one arrangement, the Rogowski coil is formed about a split helical structure such that the ends of the Rogowski coil are not coincident. While this does introduce a small error in the current measurement, this small error is easily correctable by calibration and/or application software. The current sensor includes suitable insulation such that it can be placed about energized, high-voltage lines.
