Electronic charge exchange at insulator-insulator interface in insulating composites
Proceedings of 1994 4th International Conference on Properties and Applications of Dielectric Materials (ICPADM), 2002The charge exchange at the insulator-insulator interface in insulating composites is affected by the direction of the carrier transport and carrier species. In this paper the charge exchange process at the PS-PMMA interface was discussed on the basis of asymmetric photoconduction and contact charging.

The breakdown of composite insulation
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1972, 1972It is frequently assumed that composite insulation, consisting for example, of a column of air in series with a solid dielectric, breaks down because a discharge in the weaker gaseous section acts like a thin conducting extension of the electrode.

Installing insulation jacket to improve outdoor insulation performance of composite insulator
IEEE Transactions on Dielectrics and Electrical Insulation, 2011In the paper, a new approach is proposed to improve the outdoor insulation properties of transmission lines. It is achieved by installing the insulation jackets and additional grading rings onto transmission line conductors. The impact of insulation jacket parameters on the electrical field distribution along a 220 kV composite insulator was simulated ...

In contrast to composite long rods, composite post insulators are subjected mainly to loads which act perpendicular to the longitudinal axis of the insulator and thus produce bending stresses over the cross-section of the insulator. As a result of this bending load, composite post insulators use FRP rods of substantially greater diameter compared to ...

Swedish research on the application of composite insulators in outdoor insulation
IEEE Electrical Insulation Magazine, 1995Swedish research on the use of composite insulators in outdoor insulation focuses on investigations in natural and artificial conditions, new diagnostic test methods, and the effects of ageing and hydrophobicity variations. Basic flashover phenomena on hydrophobic surfaces also are being studied. >

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.

Characteristics of Composite Insulation: Liquid-Impregnated Insulation
IEEE Transactions on Electrical Insulation, 1986A description is given of composite insulation, i. e. swelling of polymers by oil, oil streaming electrification of solid dielectrics , and V-t characteristics of LN2-impregnated insulation due to partial discharge. Swelling can be accelerated by ultrasonic wave irradiation. This reduces the saturation time.
