High-voltage power-transformer insulation

Proceedings of the Institution of Electrical Engineers, 1963
The increase in transmission system voltages in recent years to 500 kV, with even higher prospective values, makes the internal insulation a large proportion of the transformer cost and therefore economically more important. The associated increase in MVA rating, and hence in size and weight, has reached beyond transport limits and demands better ...

High Voltage Insulation Failure Mechanisms

Conference Record of the 2008 IEEE International Symposium on Electrical Insulation, 2008
There are many statistics dealing with failure causes of high voltage rotating machines. While these statistics prove the relevance of the insulation as failure cause, they give little information on the real failure mechanism. This paper gives results of a research project which was launched to investigate degradation and final breakdown of the mica ...

Outdoor high voltage polymeric insulators

Proceedings of 1998 International Symposium on Electrical Insulating Materials. 1998 Asian International Conference on Dielectrics and Electrical Insulation. 30th Symposium on Electrical Insulating Materials (IEEE Cat. No.98TH8286), 2002
Composite polymeric insulators are increasingly being accepted by the traditionally cautious electric utilities worldwide. They currently represent about 70% of installed new high voltage insulators in North America. The tremendous growth in the applications of non-ceramic insulators is due to their advantages over the traditional ceramic and glass ...

High-voltage electric insulator

2015
The invention relates to a high-voltage electric insulator (1) comprising an elongate insulating element (11) that extends along an axis and has first and second ends (117, 118) at a distance from each other along said axis, and further comprising at least first and second resonant circuits (122, 123) that are galvanically insulated from each other by ...
