Research and development results of enhancement techniques of electrical insulation performance for higher electric field application in power transmission/substation equipment, such as transformers, switchgears and cables, are described, especially based on the view point of dielectric materials. Firstly, the electric field analysis, field optimization and field measurement techniques are introduced...
High voltage rotating machines are supposed to be optimized not only in terms of performance but among others also with respect to space and material utilization. When designing machines there has been considerable effort made to reduce the overall size of generators particularly in the axial direction. The winding is one of the more demanding parts of the generator but the end winding is an obvious...
