This project aims to improve asset management capabilities in line with the Smart Grid principle, for example more intelligent monitoring of assets’ remaining life. Prognostics and Health Monitoring (PHM) is, broadly speaking, the science of analysing the operating and environmental parameters of a system and using those data points to predict the remaining useful life (RUL) of the system.
Initially, a literature review of the science of PHM will be conducted to identify optimal tools for determining asset health and forecasting RUL. Knowledge from the review will be applied in the development of a small scale condition monitoring and prognostics system for predicting the RUL of an electromagnetic relay with a failure history which appears to exhibit a correlation between life expectancy and the applied voltage.
Subsequently, an online oil condition monitoring and prognostics system prototype will be developed incorporating a dedicated intelligent sensor system with data handling and communication capability. Once tested in the lab and optimised, the prototype will be demonstrated on decommissioned transformers in SHE Transmission’s licence area.
