Insulation Hysteresis in Micaceous Composites
IEEE Transactions on Electrical Insulation, 1982The dissipation factor, sensitive to voltage stress, is invariably used for quality assessment of high voltage rotating machine insulation. When it is subjected to higher electrical stresses, insulation hysteresis occurs during these measurements, which is similar to those exhibited by ferromagnetic materials. The influence of the insulation hysteresis

Natural, Rotationally Asymmetric Ageing of Composite Insulators
Conference Record of the 2008 IEEE International Symposium on Electrical Insulation, 2008The market for polymeric insulators has existed for over 20 years and the possibility now exists to compare good quality service-aged products with the original expectations of performance. This paper presents investigations of field-aged insulators, which have been deployed for 6-7 years on a variety of distribution lines.

Polymer‐Based Nano‐Composites for Thermal Insulation
Advanced Engineering Materials, 2019The growing need for efficient energy use prompts for effective thermally insulating materials. Nano‐composites represent an important class of materials able to fulfill these needs, enabling both sizeable energy savings and specific applications where thermal insulation has to be coupled to mechanical robustness and lightness, like in automotive and ...

Hydrophobicity and insulated resistance of composite insulators with biological contamination
2016 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2016Biological growth has been observed on insulators installed all over the world. However its impact on the electrical performance is not well known. This paper described the investigations on the performance of post insulators with biological growth at a converter station. Both the ceramic and composite insulators were investigated.

Composite Insulating Materials and Systems
1983Composite insulating materials are at least an order of magnitude more diverse and perhaps as much more complex in their behavior than simple one-component materials. This makes the preparation of a one-chapter summary of their electrical properties perhaps more difficult but, on second thought, somewhat simpler.

Partial discharge measurements and insulation diagnoses of solid insulating composites
Proceedings of ESMO'95 - 1995 IEEE 7th International Conference on Transmission and Distribution Construction, Operation and Live-Line Maintenance, 2002The method and techniques of partial discharge measurements for solid insulating composite tubes were studied and some tubes were used to measure PD quantities. It was found that PD measurement was a sensitive and reliable diagnostic means for detecting internal insulation defects and evaluating property charges of solid insulating composite materials ...
