A CORELESS CURRENT PROBE AND A METHOD OF MEASURING CURRENT |
摘要 |
A coreless current probe has a body defining an opening in a plane and a central line through the opening which is normal to the plane. A conductor carrying a current to be measured can be accommodated in the opening. At least three coreless single point magnetic field sensors are distributed in the body around the opening. The linear spacings between adjacent sensors around the opening are not all the same. In another embodiment, the sensors are not all located on a common cylindrical surface. One embodiment has a U-shaped body enabling engagement with a current carrying conductor. The sensors are arranged so that the sum of the outputs each with appropriate weighting is zero in any homogenous field. The sensors outputs have differing weightings so as to maximize rejection by the probe of external magnetic fields. |
