5 Transformer Fleet Management with e-terraassetcare Integration of three processes and tools AIM Process 3 Steps condition assessment + Field Mobility Tool Structured data collection + e-terraassetcare Information & Analytics

6 Transformers Condition Assessment: an exhaustive assessment BUSHING CONDITION DLA, Capacitance, oil leaks, physical condition assessment OIL LEVELS OLTC CONDITION Maintenance, Contact condition, Oil Condition. TANK CONDITION Leaks, rusting, paintwork condition ACTIVE PART DGA, Electrical test Results, Cellulose insulation condition OIL CONDITION Moisture, Physical/Electrical condition, Corrosive sulphur COOLER BANK CONDITION Pumps, rusting, fans, valves

7 ALSTOM Grid transformer condition assessment A 3 steps process No outage Level 1 Assessment Oil Testing & External Condition Assessment Electrical Testing required? Assessment & Recommendations Minimum outage Level 2 Assessment - Electrical Tests Internal Inspection required? Assessment & Recommendations Outage required Yes Level 3 Assessment - Internal Inspection Assessment & Recommendations

8 Alstom Grid Level 1 condition assessment Level 1 Assessment (Outage not required.) Oil Samples and tests in Laboratory External Condition Evaluation Assessment of Historical. Oil Test Results. Electrical Test Results. Service History. Deliverables Basic transformer condition, The report will: Detail urgent maintenance. Define maintenance scope for future scheduled outages.

9 Alstom Grid Level 2 condition assessment Level 2 Assessment= Level 1 + Electrical Tests Routine Tests Ratio Winding Resistance Insulation Resistance Polarization Index Winding and Bushing Power Factor Other advanced Tests RVM - Recovery Voltage Measurement FRA - Frequency response analysis Special advanced Tests Partial Discharge tests Deliverables Transformer condition, including bushings and windings Estimated residual life, even if not conclusively. The report will: Highlight deviations from expected electrical parameters and remediation Detail transformer areas where further investigations are required.

10 Alstom Grid Level 3 condition assessment Level 2 + Internal Inspections Incl. paper samples for DP analysis. HV Leads Tapchanger Diverter Core Windings Tap changer Selector Tap Leads Deliverables Oil Insulation Paper Insulation Assessment of the current transformer condition with good knowledge of the electrical & physical state of the bushings and windings. The best method to determine a transformer s remaining life and any required remediation actions.
