    Some properties of the electric vector potential, appearing in problems dealing with eddy currents induced in nonmagnetic metallic solids by the external magnetic field, are considered- The boundary condition for the electric vector potential at the boundary surface of the solid is established. The magnetic field produced by the eddy currents flowing in the solid is examined. An interpretation of ... View full abstract»

    In order to determine the stremes in high voltage DC cable accessering containing a combination of Voltalit (a proprietary epoxy Insulation), SF4 and paper/oil inxulation, a knowledge of the surface and bulk conductivily of the Voltalit is required. It ii also necessary to determine the coefficient govering the dependence of both conductivities with temperature and stress, and the variation of con... View full abstract»

    Imaging of 2-dimenslonal distributions of electric conductivity, from voltages measured on perlpheries of the distributions, is studied. It is understood that low-frequency electric currents are injected into the distributions. Optimum placement of electrodes, for maximising the value and sensitivity of voltage measurements, is studied theoretically and experimentally. The imaging theory developed... View full abstract»
