The paper describes initial research undertaken, exploring the impact of demand and other environmental factors on the power transmission network. How these factors lead to a determined probability of failure is currently determined through a set of complex equations. Demand, or loading, is expected to be the principal factor on the expected life of transmission assets such as transformers. The long-term aim of the research is to understand the likely impact of electrification of vehicles, the associated increased demand on the network, leading to the prospect of a deterioration of the network assets. This initial research suggests that transformer ageing is highly sensitive not only to the average and maximum demand in the network but also to other environment factors. Recommendations from this research will help power transmission companies to more effectively manage their assets through a more robust understanding of the ageing of assets as a consequence of Governmental policy shifts on electric vehicle uptake.
