Space charge accumulation in polymeric insulation could distort the field distribution and affect the insulation properties. In this project, charge injection and transportation inside the polymeric insulation will be investigated by numerical modelling and experimental measurements. The thermal impacts on space charge behaviours will be especially considered. A modified numerical model is expected to be built which can be used to study the charge dynamics and to anticipate the electric field variation across the insulation. In order to obtain the space charge dynamics under practical application situations, a cable PEA system is built which considering the thermal effects caused by the current flowing in the core of cable.

The proposed work will focus on the HVDC cable related properties of PP-based nanocomposites. The characteristic of the nanodielectrics interphase will be the main research object because the interphase can be the dominant factor of nanodielectrics. The proposed work will dedicate to following issues:
ââ¬Â¢ To formulate and characterise the interphase region between nano-fillers and the matrix in surface chemistry aspect. ââ¬Â¢ To investigate how the surface state of nano-fillers affect the polymer-filler interphase. ââ¬Â¢ To investigate the role of the interphase in determining the properties of nanodielectrics

This project has been investigated thermal ageing effects on the changes in physicochemical and electrical properties of polyethylene widely using in the high voltage cable. The project, in particular, contributes to more understanding the changes in charge transport dynamics associated with the different ageing formation and concentration depending on the ageing procedure, temperature and controlled morphology of the polyethylene (HDPE and LDPE blended polyethylene).

The aim of this project is to develop a multiphysics model of a HTGR gas turbine power station. Particular attention will be paid in selection of Printed Circuit Heat Exchanger (PCHE) design as well as working fluid. The study will investigate performance of various geometry of heat exchanger aligned with working fluid. Different shape of channels as well as various working fluids become interesting challenges to be analysed. Thermal energy optimisation from selected PCHE and working fluid and Closed Brayton Cycle matching is another challenge. The final goal of this research is a multiphysics model for HTGR gas turbine power plant with the best PCHE and working fluid performance.

In order to improve overall HV plant efficiency, there is increased use of thermosyphon technology to provide temperature control, replacing conventional pumps, fans and radiators. Hydrofluoroethers [C4F9OCH3] and Fluorinated ketone [CF3CF2C(O)CF(CF3)2] are two low global warming potential coolants. One use of these fluids in high voltage plant is as the coolants within a thermosyphon. This project aims to characterise the dielectric properties of the candidate coolants and their coupled thermal-electrical performance.

his project aims to investigate the characteristics of the plasma generated by the use of a carbon films in a Triggered Vacuum Gap. Various different types of carbon film with different thicknesses and preparation techniques will be used to obtain the required data. This should allow for future devices to be engineered to more efficient designs with the increased understanding of the physical mechanics involved with the operation of this kind of device.

This project is concerned with the development of techniques to identify transformers at risk of catastrophic failure due to the presence of corrosive compounds in the insulating oil. Work will concentrate on further development of techniques to measure corrosive sulphur content in the oil with the aim of producing an on-line data acquisition system that will allow the changes in copper concentration and sulphur concentration to be measured in real-time on in-service plant. The ultimate aim being to develop prognostic tools that can be widely applied to electrical transmission networks to reduce the risk of unplanned outages.

Within the European GIESEPP project, investigations of the operation of the thrusters with alternative propellants will be performed to ensure their functionality. A combination of analytic modelling and experimental testing will be used to evaluate the impacts of alternative propellants to achieve the objective of reducing the dependence of electric propulsion systems from the expensive and limited Xenon.

This project is concerned with using machine learning to identify potential operational issues among National Grid's 700+ 400/132 kV autotransformers. One tool for condition assessment is dissolved gas analysis of oil samples from operational transformers. Oil samples are typically taken at 6 monthly intervals and the aim of this project is to establish from analysis of historical data whether it is possible to predict ultimate modes of failure, whether there are similarities in development of degradation mechanisms because of manufacturer, operational age, location on the network etc. and ultimately if it is possible to use current measurement data and previous data trends to predict future issues within the fleet.
