This project is a collaboration with Liverpool Universitys Centre for Intelligent Monitoring Systems who have developed an analysis technique based on the Chromatic analysis of various materials. The technique uses ordinary white light from any source as a stimulus and analyses the frequency and intensity of reflected light from the visible to near-infrared part of the spectrum to determine any changes in the state of the material. This project is based on using this technique to analyse mineral insulating oil with the objective of providing an alternative non-intrusive optical method for oil analysis.
The project aims are to establish if small changes in the optical signal of the oil caused by increased attenuation that would be indicative of chemical degradation by whatever mechanism can be detected, establish if any changes in the optical signal can be related to known degradation mechanisms and to establish if this can this be done through the oil-level site glass.
