    Ageing is a gradual change of state and property that usually leads to a degree of malfunction. The primal process in all cases is that the chemical and physical bonds between the atoms of the substance are repeatedly broken, reorganized, and reformed in new configurations. The author lends considerable insight into the mechanics of ageing, especially electrical failure involving insulation. View full abstract»

    This paper discusses ozone synthesis by employing a short duration (∼120 ns) of pulsed power and using positive voltages in dry air and in oxygen, with and without a dielectric barrier. Ozone concentration and ozone production yield (efficiency) are measured at various peak pulsed voltages, pulse repetition rates, varying input energy densities, and different gaseous gap spacings.

    In modern distribution cables, the stress control layers extruded over the conductor and insulation play a critical role in protecting the insulation from stress caused by the conductor, shield wires, tapes, etc. This paper considers the requirements for the conductor and ground shield stress control layers. Finite element analysis suggests that a resistivity of 500 Ω-m is too high a resisti... View full abstract»

    Cycloaliphatic epoxy resins (CEP) have been used successfully alongside silicones and ceramics (porcelain, glass) for more than 30 years as insulation materials for outdoor applications. The authors discuss a new generation of cycloaliphatic epoxy systems with enhanced hydrophobic properties, hydrophobic cycloaliphatic epoxy (HCEP). View full abstract»
