CONDITION MONITORING IN THERMAL POWER PLANT : CONDITION MONITORING IN THERMAL POWER PLANT SHIVAJI CHOUDHURY OBJECTIVE OF CONDITION MONITORING : OBJECTIVE OF CONDITION MONITORING TO IDENTIFY CHANGES IN CONDITION OF MACHINE THAT WILL INDICATE SOME POTENTIAL FAILURE. DIAGNOSIS OF FAULT PREDICTION OF FAULT TO AVOID FURTHER DAMAGES TO PLAN BETTER SPARE MANAGEMENT OUTAGE OF EQUIPMENT CAN BE BETTER PLANNED. ENHANCING THE MACHINE EDURANCE LIMIT. LESS DOWN TIME AND MORE PRODUCTIVITY GREATER SAFETY TO WORK FORCE. MONITORING TECHNIQUE : MONITORING TECHNIQUE VIBRATION MONITORING. LUBRICANT ANALYSIS. NOISE ANALYSIS. WEAR DEBRIS ANALYSIS. THERMOGRAGHY. D G A. NDT ULTRASONIC VIBRATION ANALYSIS : VIBRATION ANALYSIS TURBINE. GENERATOR. PUMP. MOTOR. FAN. COMPRESSOR. VIBRATION DIAGNOSIS : VIBRATION DIAGNOSIS SHAFT AND ROTOR- UNBALANCE , BENT, MISALIGNMENTS BEARING –DAMAGES,,DISTORTION,LOSS OF LUBRICANT. GEAR –TOOTH MESHING FAULT,WORN TEETH,MISALIGNMENT MECHANICAL LOOSNESS LUB OIL ANALYSIS : LUB OIL ANALYSIS MOISTURE MECHANICAL IMPURIRTIES DENSITY VISCOCITY ACIDITY LUB OIL DIAGNOSIS : LUB OIL DIAGNOSIS DEGRADATION OF LUB OIL IMPURITIES IN LUB OIL WEAR DEBRIS ANALYSIS & DIAGNOSIS : WEAR DEBRIS ANALYSIS & DIAGNOSIS WEAR DEBRIS CARRIED OUT FOR WEAR PARTICLE CONCENTRATION IN OIL CONDITION OF LUB OIL OUTSIDE CONTENMATION TO DETERMINE TO WEAR CONDITION OF MACHINE NORMAL RUBBING BEARING FAILURE CONDITION OF GEAR CUTTING OF METAL THERMOVISION MONITORING : THERMOVISION MONITORING IDENTIFICATION OF HOT SPOT . USED FOR MONITORING OF SWITCHYARD EQUIPMENT. ROUTINE MONITORING OF MOTOR/PUMP. MONITORING OF DRAIN PIPES LINES TO DETECT CHOKING OF PIPE LINES. TO MONITOR OF CONDITION OF INSULATION ON PIPE AND EQUIPMENT. DISSOLVE GAS ANALYSIS : DISSOLVE GAS ANALYSIS FOR ALL TRANSFORMERS. DIELECTRIC STRENGTH OF TRANSFORMER OIL.
