AIMS

The sole aim of power generation is to meet the electricity needs of consumers spread across homes and industries. This generated power meets different consumers at different voltage levels, and transformers are generally the equipment designed to supply the needed voltage to consumers. Transformers are expensive essential components of high voltage (HV) stations. They have extended mean-time-to-repair (MTTR) and enormous maintenance costs. Transformer failure can amount to the shutdown of the power station, which has serious economic consequences. Other consequences could include the loss of life, substation equipment, and environmental (ecological) consequences. 

Transformer oil insulation failure has rippling consequences on the primary purpose of power generation, the safety of personnel and the work environment, and enormous economic consequences. Consequently, their volume, purity, and reliability cannot be compromised. Ageing in transformer oil is primarily evidenced by interfacial tension and acidity. The transformer ageing detection method is classified as either intrusive or non-intrusive, destructive or non-destructive, offline or online. Intrusive detection techniques make contact with the transformer oil as opposed to non-intrusive methods. Destructive methods alter (in the short or long-run) the transformer oil properties being measured as opposed to non-destructive methods. The online detection method involves live ageing detection of the transformer oil while operating as opposed to offline ageing detection, which only involves sample collection for laboratory analysis and interpretation.

Previous works have centred on the discovery and modification of ageing detection sensors for increased sensitivity , offline assessment of aged samples by directly monitoring the growth of these ABPs or indirectly monitoring the influence of these ABPs on source inputs , and chemical sensor developments for detection of several ABPs. In this project for the first time the focus will be on implementing an online ageing assessment sensor for transformer oil. Furthermore, there has been little research on IoT integration to transformer oil online ageing systems for real-time ageing detection. This work will develop a nouvelle online ageing measurement instrument for transformer oil insulation that reports real-time TAN, IFT and other characteristic values.
