    In this paper, as a result of their laminar structure, dry BOPP windings have substantially anisotropic thermal conductivity. In the plane of the film, the thermal conductivity is about twice that of bulk polypropylene and about three times the thermal conductivity through the plane of the film. Three-dimensional finite element computations demonstrate that the anisotropic thermal conductivity of ... View full abstract»

    This article is the second of a series of three examining on-line partial discharge monitoring of Type I motors and highlighting critical aspects of IEC technical specification 60034-18-41. Motors passing the off-line type test can still experience premature failure when driven by variable-speed drives. View full abstract»

    In this article, changes in FRA signatures due to changes in temperature of transformers and in the moisture content of their insulation have been presented and discussed. In the authors' experience, changes in FRA signatures as a result of changes in transformer temperature and moisture content follow a common pattern, independent of the type of winding. However, the magnitude of the changes depe... View full abstract»

    The underground cable simulation model discussed in this paper evaluates, accurately and efficiently, numerous budgeting scenarios and their effects on the underground cable reliability and faults. This in turn enables proactive approaches to cable replacement management and a focus on budgeting optimization throughout the duration of the cable replacement project, rather than short term. For util... View full abstract»

    In this paper, a model for a spherical cavity within a homogeneous dielectric material was developed using finite element analysis (FEA) software. The model was used to study the influence of different cavity conditions on local electric field distribution and consequent PD activity. The study involved variation of cavity diameter and cavity location within the dielectric material. In addition, ex... View full abstract»
