Sustainable operation of transformers with better understanding of technical and economic constraints. Transformer failure can be devastating to consumers and network service providers, costing from thousands to millions of dollars in transformer replacement and lost productivity. To avoid such catastrophic failures, the goal of this project will be to develop new methods that can maximise transformer usage and minimise cost before failure occurs.
Investigation of key factors affecting the polarisation based diagnostics of power transformers. To avoid system wide power interruptions, major assets in the electricity network must be always operating satisfactorily. One of the key assets in the electricity network is the power transformer. Currently many transformers are over 50 years old and failure of a transformer may result in long interruptions in supply and the loss of millions of dollars in revenue. The ageing of transformers needs to ....Investigation of key factors affecting the polarisation based diagnostics of power transformers. To avoid system wide power interruptions, major assets in the electricity network must be always operating satisfactorily. One of the key assets in the electricity network is the power transformer. Currently many transformers are over 50 years old and failure of a transformer may result in long interruptions in supply and the loss of millions of dollars in revenue. The ageing of transformers needs to be properly monitored to avoid catastrophic failures. This project will provide an innovative solution for the better understanding of the ageing processes of transformers and help
managers make correct decisions for maintenance and replacement strategies.

Condition Assessment of Medium-Voltage XLPE-Insulated Cables Degraded by Water Treeing. In Australia degraded underground XLPE cables are causing disruption of electricity supplies and high community costs. There is no reliable non-invasive technique for prediction of cable condition to optimise cable replacement and refurbishment. In this project a large-scale experiment will be undertaken on 22 kV cables to ascertain the effectiveness of a new cable refurbishment technology.

In Australia degraded underground XLPE cables are causing disruption of electricity supplies and high community costs. There is no reliable non-invasive technique for prediction of cable condition to optimise cable replacement and refurbishment. In this project a large-scale experiment will be undertaken on 22 kV cables to ascertain the effectiveness of a new cable refurbishment technology. New techniques for assessment of cable condition will be developed using unique data from the ageing experiment and computer models of fundamental phenomena. Successful conclusions from this project will save the industry partner and other electricity distribution companies tens of millions of dollars.Read moreRead less

This project aims to develop, implement and test an innovative state estimation algorithm for monitoring low voltage electricity distribution networks. The proposed system is an essential step to enable a range of smart network applications to manage peak network loads and increasing amounts of solar photovoltaic generation. The project includes a prototype application and field trial for managing the operational state of part of the network to keep within safe loading limits. It may also facilitate future new technologies such as demand-side management, energy storage and electric vehicles. By managing peak loading, the project could defer or eliminate capital-intensive network augmentations and associated customer electricity price increases.Read moreRead less
Bushfire safety improvements for rural electricity networks using hybrid fault detection incorporating distributed observations of travelling waves. Electrical faults in distribution networks can result in catastrophic bush fires. The existing fault detection methods are known to be incapable of detecting many faults. This project will develop improved protection methods that detect travelling waves produced by dangerous faults such as fallen lines and vegetation contacts.
Electrical insulation diagnostics for high voltage power cable systems based on voltage excitation at very low frequency. High voltage power cable systems rely on their insulation to withstand very severe electric stress without breakdown. Field testing of cables at normal frequency is not feasible, but with very low frequency excitation from mobile sources such testing is possible. The overarching aim of this project is to develop methods for interpretation of results from such measurements. It ....Electrical insulation diagnostics for high voltage power cable systems based on voltage excitation at very low frequency. High voltage power cable systems rely on their insulation to withstand very severe electric stress without breakdown. Field testing of cables at normal frequency is not feasible, but with very low frequency excitation from mobile sources such testing is possible. The overarching aim of this project is to develop methods for interpretation of results from such measurements. It is intended that this will enable formulation of appropriate test procedures and better assessment of insulation conditions in service-aged cables. Also of considerable significance to fundamental research will be the project’s goal of a better physical understanding of insulation material behaviour when subject to very low frequency electric stress.Read moreRead less
