“…Its hydrophobicity, light weight, high durability and better performance in polluted conditions have made polymers advantageous over other materials such as porcelain and glass [1][2][3]. However, the outdoor composite insulators are vulnerable to flash over, surface breakdown, corona and dry band arcing at service conditions.…”

Power distribution and transmission networks widely adopt composite insulators for the overhead power line applications. The premature failure of these insulators due to the high electric field induced in them has become a major disappointment in the recent years. In this paper, an 11kV composite insulator is modelled in a three phase high voltage environment, and the induced electrical field is studied using finite element analysis. To reduce the computational time and resources, a simplified geometry for the insulator is also proposed. The electric field calculations are used to understand the importance of using a three phase supply in computational and experimental analysis of insulators, which we determine is more accurate than using a single phase supply.

“…While there is a desire for new insulation materials with beneficial properties [14,15], a comprehensive understanding of the long-term dielectric performance is yet to be realized. In particular, the interaction between environmental and electrical aging factors is complex and not fully understood [16].…”

Delivery of the Smart Grid is a topic of considerable interest within the power industry in general, and the IEEE specifically. This paper presents the smart grid landscape as seen by the IEEE Dielectrics and Electrical Insulation Society (DEIS) Technical Committee on Smart Grids. We define the various facets of smart grid technology, and present an examination of the impacts on dielectrics within power assets. Based on the trajectory of current research in the field, we identify the implications for asset owners and operators at both the device level and the systems level. The paper concludes by identifying areas of dielectrics and insulation research required to fully realize the smart grid concept. The work of the DEIS is fundamental to achieving the goals of a more active, self-managing grid.

“…Porcelain as an insulating material has over one century of service history, while polymer materials have only three decades. Early generation polymer products did not provide the expected service life, and users still have concerns about polymer insulating material performance [2]. Early polymer products did not provide the expected service life, primarily because of inadequate UV, tear or hydrolytic resistance.…”
