Transformers are essential for modern power distribution system. They are efficient and enable the voltages to be transformed up for transportation of electricity and back down for consumer use. The reliability of the transformer is affected by faults and fatigue of the copper. The bigger faults a transformer is subjected to, the shorter life time it will have due to damage to the winding and other parts of the transformer. This thesis investigates if it is possible to characterise the noise made from the windings during a short circuit fault or lightning strike, to see if it can be replicated and if transformers can be diagnosed with the help from the noise. Faults creates forces on the windings, these forces can be so great that the windi...
