Due to the degradation of power transformer under its normal and abnormal operating conditions, maintenance activities are vital to restore the condition. However, the preventive maintenance costs are now of primary concern. The scattering failure data are systematically recorded and analyzed to determine the critical component of power transformer. Two transformer models of rated voltage 115/22 kV and 230/115/22 kV have been chosen in this study. The determined critical component with high… CONTINUE READING
