Performance Analysis of Composite Insulators
2019 IEEE 3rd International Electrical and Energy Conference (CIEEC), 2019Composite insulators are widely used in high voltage transmission lines in coast and polluted areas due to excellent pollution flashover resistance, high strength and convenient installation and maintenance. While there are still various kinds of defects such as abnormal temperature rise, aging of materials even fracture in the existing composite ...

Composite insulators and their aging: An overview
Science in China Series E: Technological Sciences, 2007The aging (biological deterioration) is a major problem of composite insulators now-a-days. The main thing in aging is to predict how, when and with what speed it occurs and under what conditions it can lead to failure and what overall average expected life of a composite insulator is. For this a lot of researches have been done. This review summarizes

Composite Insulation for a Power Cable
International Journal of Electrical Engineering & Education, 1985Composite insulation for a power cable A relationship is derived for the voltage of a power cable containing three different insulating materials, allowing for a safety factor in the withstand voltage of each insulator layer and assuming that the electric fields in the dielectrics do not exceed a prescribed ...

Sound insulation of composite materials
Composites, 1974Abstract The relationships between a material's physical properties and its sound insulation are discussed. The sound insulation of composite materials can be estimated provided that these physical properties are known. Although composites may be designed to give a better than average sound insulation performance for their mass, the sound insulation ...

Composite Hollow Core Insulators
2013Composite hollow core insulators (referred to hereinafter as HCI for short) are used primarily as housings for various high-voltage equipment and apparatus. Owing to their conditions for use, they primarily have to withstand bending and compression loads and since a large number of the electrical equipment are gas insulated (with SF6 and SF6 gas ...

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

Approaches to aging of composite insulators
Proceedings of the 6th International Conference on Properties and Applications of Dielectric Materials (Cat. No.00CH36347), 2002Composite insulators, especially those based on silicone rubber, exceed the traditional ceramic or glass designs in many aspects. On the other hand, in common with other polymer insulating materials, the composite insulator suffers from inevitable deterioration and aging.

Impacts of corona rings on the insulation performance of composite polymer insulator strings
IEEE Transactions on Dielectrics and Electrical Insulation, 2015Corona rings can improve the insulation performance of insulator strings because of their electric field grading property or can decrease the insulation performance due to their arc clearance reduction property. The resulting insulation performance of the string which is under the influence of those two conflicting effects depends on the corona ring ...
