Abstract
Rogowski coils are special types of mutual inductors often used to measure high AC and transient currents. Traditional designs are reviewed. The significant sources of error associated with typical coil designs are examined. A “machinable Rogowski coil” is introduced and discussed. The reasoning behind critical design choices is discussed. The improved performance of the machinable coil is compared to that of other designs. Test and calibration methods are discussed
