“…The findings of this study are consistent with many published results of previous studies on hydrophobic cyclo-aliphatic epoxy. As expected, standard CEP, which is not designed to yield a hydrophobicity transfer effect, showed higher leakage current activity than other tested materials [16,17] .…”

The 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 the methods of artificial field testing (aging), natural testing, standards the developed for aging, techniques of analysis, results achieved until now about various parameters from various locations, handling guidelines and a conclusion on what is further needed.polymeric insulators, aging, composite, SEM

“…The mold line protrusion has been reported in literature [12] to appear as a weak point in an insulator's design. The electric field analysis of the jumper loop 132kV insulator shows that the presence of the mold line can significantly enhance the local electric field by more than 50%.…”

Abstract-A COMSOL multiphysics electric field analysis of an ethylene-propylene rubber (EPDM) insulator is presented. The 132kV insulator is an inverted post insulator that is taken from a jumper loop. It has been in service in a severely polluted environment for eight years. The insulator's surfaces are asymmetrically aged with organic dark deposits covering the insulator's surface, and with additional surface markings. The insulator has a manufacturing artifact, known as the mold line, which forms an elongated protrusion along the length of the insulator. This artifact is introduced into the COMSOL model to investigate its effect on the local electrical field. The reason for this study is that the area surrounding the mold line is lighter in color, with markings that suggest discharge activity. The regions of the localized field enhancements are identified and correlated with the ageing features, such as hydrophobicity loss, surface roughness and discoloration observed after eight years in service. A discussion whether the environment or the electric field are dominating the ageing process of the insulator is included.

“…Among their advantages, which include reduced size, weight and breakage, polymer housed surge arrester failures are nonfragmenting with no sharp porcelain fragments to impact nearby equipment and personnel [11,12]. This single advantage alone has greatly spurred their widespread use.…”

This article presents a comparative experimental investigation of surge arrester (SA) performance under clean, unpolluted and polluted conditions. Three different surge arresters rated 33 kV and 10 kA were tested to investigate how the internal active material (either zinc oxide/metal oxide, ZnO, or silicone carbide, SiC) and the arrester housing material affect the overall performance under clean and pollution conditions. Both AC and impulse tests were conducted on SiC porcelain-, ZnO polymeric-, and ZnO silicone-rubber-(composite insulator) housed arresters. In the case of AC application, both the internal and the external currents were measured, while the discharge current is measured under impulse voltage application.
