Abstract: This paper describes the condition monitoring of Transformer winding. Condition Monitoring means capable to predict health condition of the electrical machine. A successful continuous condition monitoring scheme for electrical machines offers significant advantages, since it would be capable of providing adequate warning of failures of a variety of its components and would enable maintenance to be scheduled most effectively. In diagnosing faults in electrical machines, research has focused on parameters such as, insulation, capacitance, temperature, phase angle etc. In this paper a test procedure has been establish to determine the phase difference accurately. Based on this phase difference, the capacitance of the transformer winding has been calculated. The value of the capacitance basically indicates the insulation of the transformer winding. Accelerated life testing arrangement conducted to transformer winding, from this accelerated life test, approximate prediction of life of insulating material has been analysed. As the paper describes the continuous monitoring of transformer winding, so the ageing and the winding deterioration of transformer can be detected
