ABB LEAP Scope Of Work (Level 2 Or Standard)Document Transcript
1. Scope of WorkScope of work comprises of: 1.1. INSPECTIONS AND MEASUREMENTS AT SITE LEAP Standard on Stator Windings Consists of the following measurements and analysis 1.1 Polarization De-Polarization Current Analysis (PDCA) 1.2 Measurement of Capacitance and Tandelta 1.3 Recording of Partial Discharges & analysis 1.4 Non-Linear Behavior Analysis 1.5 Winding Resistance Measurements 1.6 Life Expectancy Analysis 1.2 ANALYSIS AND RECOMMENDATIONS The submission of data consists of: (a) Interpretation and reporting of tests results and analysis, which will include defect identification, its severity, possible causes and effects (b) ABB will provide recommendations based on the study of measurements and analysis for extending the life and/or improving the reliability and availability of the stator windings tested, and will consist of: • Recommendations for maintenance, including the development of a maintenance and inspection plan, which could also include major repair/modification/part replacements as required, in order to extend the estimated life of the stator winding insulation. • The life expectancy analysis of the stator winding insulation based on the existing operating conditions, and after suggested maintenance recommendations.
