A current sensor for measuring one or more air flows from a source to a load protencia; The sensor comprises: (a) an input for connecting to the source;(b) output for connecting to the load; (c) one or more Conductive Lines (49th, 94B, 94c; 250260) connected between the input and output or to guide the current flows through the sensor; and (d) one or moreNsores (70) to detect one or more local Magnetic Fields generated around the line (94250260) by Current flowing through there,Thus provides a measure of current indicative of the magnitude of the current or Currents.The sensor is Distinguished because it comprises a Plurality of elements of corrient CoilAnd elongated (78) arranged in a common Plane substantially and arranged to be substantially insensitive to Magnetic Fields generated remotely and respond to Magnetic Field or theLocal Magnetic Fields to generate the current Measurement; The Coil elements are arranged in (78) areas (75,76,77) that are more than two effective centres and Exhibit mutually opposing Responses to remote Field.
