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.
