CONDITION MONITORING OF POWER TRANSFORMER USING FAILURE MODES AND EFFECTS ANALYSIS (FMEA) by Jaspreet Kaur
This thesis presents condition monitoring of power transformer using failure modes and effects analysis (FMEA). The power transformer plays an important role in the efficiency and reliability of power transmission network. Power transformers are also the most expensive network equipment. Many faults occur in the power transformer, the affect of which can be from mild to severe. So, it is necessary to monitor the condition of power transformer using failure modes and effects analysis (FMEA) technique. FMEA is a procedure to identify and assess consequences or risk associated with potential failure modes. It assigns a numerical value (Risk Priority Number), which is determined by each risk factor’s occurrence (O), severity (S) and detection (D). The output of FMEA technique could be graphical charts, worksheet tables and matrices to sort the most critical components. Recommendation of remedial actions for each failure mode has been given to improve the availability and reliability of the power transformer.
