ABSTRACT:
An apparatus is provided for measuring the test current in magnetoelectric fault detection, for instance by the magnetic particle method. A sensor comprising a Hall generator or a magnetoresistor is movably mounted on a diamagnetic support which clamps the sensor at a variable distance from a conductor carrying the test current. Alternatively, a plurality of sensors can be fixed to the support and the appropriate sensor selected for use.
