The thesis proposes an approach to the protection of Power Transformers using a MEMS sensor system to augment or replace existing protection techniques. Traditional technologies used for protection and analysis involves pressure and temperature sensing, gas chromatography and/or a Buchholz relay. The proposed MEMS device is attached to the windings immersed within the insulating oil, and primarily consists of multiple micro scale turbines centrally shafted to a MEMS generator. The device utilizes relative differences in velocity, pressure and flow rate, of fluid emanating from stressed insulation. The emanated energy is reciprocated to an electrical output of the MEMS, and RF coupled to an external user interface for active monitoring.
