Abstract
An instrument () for measuring the loss factor of an electrical apparatus () having an axially extending elongate geometry, in particular a medium voltage cable, comprises: at least a first and a second sensor (A,B) connectable to the apparatus () in a first and a second measuring section (A,B) axially spaced along the apparatus () by a predetermined quantity, respectively, and designed to measure respective values of the magnetic field generated outside the apparatus () by a load current flowing axially through the apparatus; a processing unit () designed to receive the magnetic field values measured by the sensors (A,B) and programmed to derive from them a load loss value as a function of the difference between the measured magnetic field values.
