BACKGROUND

High voltage outdoor insulators play an important role in the safe and reliable transmission of power. Although the cost of insulators in an overhead transmission line project may be as low as 5% of the total cost of the network, their performance is of vital importance in power system. In recent years, superhydrophobic coatings have been developed with intrinsic properties of self-cleaning, self-healing, icephobicity, high thermal conductivity, and relatively higher permittivity and dielectric strength. The self-cleaning and low wettability properties of superhydrophobic surfaces can be exploited to reduce surface contamination on outdoor insulators. Although there is a lot of interest in investigating techniques and methods for preparation of superhydrophobic coatings for different applications, there is very little research on the feasibility of superhydrophobic coatings for outdoor high voltage insulation.

AIMS

This project will look at the performance of superhydrophobic coated outdoor high voltage insulators under different electrical, chemical and environmental conditions. The dielectric properties of superhydrophobic coated insulators such as flashover voltage, leakage current, surface resistance will be investigated under various environmental and polluted conditions. The project will also look at the comparative performance of different high voltage insulator such as glass, ceramic and polymer when coated with superhydrophobic materials. 

THE CANDIDATE

The successful candidate should be able to demonstrate a solid background in at least one of the aspects: electrical power engineering, high voltage engineering, material sciences or relevant. Candidates with experience in a high voltage lab setting will be given preference. However, full training will be provided for working in the high voltage lab.

Previous experience of publishing in journals or international conferences is not essential but advantageous.
