1) Condition Assessment of stator windings with LEAP Standard Package and end winding assessment. 2) LIFE Expectancy Analysis with 85% confidence level. 3) The tools used to derive the results are PDCA, Tan Delta & Capacitancemeasurement, Non Linear Insulation Behaviour, Partial Discharge Analysis & Bump test on stator end windings .4) To perform this test the machine has to be partially dismantled(i.e.,opening of end covers) and requires 4-5 days outage.
