Organization & Objectives
SmartLife
Guillaume & SmartLife Core Group – France – S1 – Paper 1095
SmartLife = collaborative exchanges through a large networking of Utilities & Instituts
26 partners from 9 countries
12 DSOs, 6 TSOs, 5 R&D, 3 Universities
Consortium Committee, Core Group, User Groups
60 experts & asset managers
Exchanges = sharing of data / knowledge / practices
Identify best practices
Prepare / launch common actions
Frankfurt (Germany), 6-9 June 2011SmartLife

Cable systems : some key results
SmartLife
Guillaume & SmartLife Core Group – France – S1 – Paper 1095
Failure analysis
Good aging of both paper & polymeric links
Database to improve statistics on technologies & failures
Failure & aging mechanisms
Partial discharges for paper cables (thermal & mechanical constraints)
Water-treing for polymeric cables (water ingress & insulation imperfection)
Lab tests
Common procedures on samples removed from the field
Common database for sharing of test results
Frankfurt (Germany), 6-9 June 2011SmartLife
Cable systems : some key results
SmartLife
Guillaume & SmartLife Core Group – France – S1 – Paper 1095
Health Index
Potential powerful tool to represent overall health of equipment
Need of development vs. data quality to help define AM policies
Diagnostics
Applied by utilities as potentially useful to determine link condition
Need of improvement to really support AM decisions (lifetime extension)
Technical specifications
International standards as a minimum quality level of equipment
Need of complementary tests to reach the required quality level
Frankfurt (Germany), 6-9 June 2011SmartLife
Power Transformers : some key results
SmartLife
Guillaume & SmartLife Core Group – France – S1 – Paper 1095
Failure analysis
Few aging allowing a real opportunity of lifetime extension
Needs of maintenance & condition monitoring & on-line diagnostics
Questionnaire to collect experience on major failure modes
Diagnostics
Lists of main techniques used & major parameters to collect
Aging mechanisms
Long term aging mechanisms important for lifetime estimation
Post mortem analysis to estimate scrapped power transformer condition
Potential innovative technologies & techniques
Frankfurt (Germany), 6-9 June 2011SmartLife
Distribution network AM : some key results
SmartLife
Guillaume & SmartLife Core Group – France – S1 – Paper 1095
Context & Practices
Generalization of Risk Management concept
Increasing focus on quality by regulators : from SAIDI to specific indicators
Needs
Network automation strategies to improve performance
Heath Index for critical equipment coherent with failure statistics
Aging models for maintenance / renewal decisions & tariff negotiation

Use: Confidential
• Both number and duration of interruptions• Premium and penalty based also on “customer willingness to pay”, much
higher for worse quality areas
