“…With the research on changes of silicone-rubber sample 's hydrophobicity under the condition of AC and DC current, Tsinghua University and other research institutions concluded that corona discharge can lead to the hydrophobicity's decline of silicon rubber material[I, [5][6]. There are also foreign scholars who did microsuructure-analysis of silicon-rubber sample after corona aging by means of SEM, FTIR, TG-OT A and GC/MS, but lack the study on the developing process of corona aging.…”

A needle-plane electrode system was used to study the characteristics of the silicone rubber under AC corona. Microstructure and chemical structure change analysis on the surface of silicone rubber after corona ageing was made by using SEM, AFM and FTIR. Infrared spectrum shows that corona would cause the rupture of fundamental chain and branched chain of material. Along with the increase of corona aging time, the content of fundamental chain and branched chain will decrease. The continuous increase in the content of carbanyl group shows the intensifying oxidation. Hydroxyl -OH turns into combined condition from dissociative condition.

Composite insulators are widely used in power systems because of their advantages of light weight, good pollution resistance, and high mechanical strength. With the increasingly serious environmental pollution problem, especially in winter at high latitudes, composite insulators are easily affected by fog, bird droppings, algae, and icing. Long-term exposure to the outdoor insulator surface will cause aging, which will then pose ae potential safety hazard to the stable operation of insulators. Therefore, the self-cleaning, anti-icing, and aging test technologies of composite insulators are particularly important. This paper introduces the research progress and current situation of self-cleaning, anti-icing surface preparation, and aging test technology of composite insulators, and looks forward to the future development of composite insulators.

“…It was found that leakage current increased with an increase in ambient temperature and applied voltage. Temperature and humidity also affected the hydrophobicity transfer characteristics of silicone rubber [32]. Therefore, enough relaxation time was allowed after each test so that a steady hydrophobicity value was achieved.…”

Leakage current is a very important parameter in the performance evaluation and monitoring of outdoor insulators. This paper presents experimental results of leakage current under different contaminated conditions of silicone rubber insulators. HTV silicone rubber sheets were utilized for tests and pollution was coated artificially in laboratory. The effect of temperature, humidity and pollution severity on leakage current of silicone rubber insulators were investigated. It was observed that leakage current magnitude increases with an increase in relative humidity, temperature, NSDD, and level of pollution severity. A discrete wavelet transforms (DWT) technique based on multi-resolution analysis (MRA) was used to study the time-frequency characteristics of leakage current. DWT-MRA technique can be used to detect frequency bands corresponding to different pollution severity levels and location of dry bands. These results can be used to predict dry band arcing activity on the surface of outdoor polymeric insulators.
