Diagnostics on insulating liquids during the life cycle of electrical equipment

Life Cycle Management (LCM) of a machine pool is an extremely complex activity that requires cross-sector skills.To adopt the best maintenance strategy, purely technical, regulatory and environmental aspects should be taken into consideration.
On the basis of the agreed duration, this course provides the tools for better managing the different phases of the life cycle of electrical equipment with insulating fluids.Each phase requires different checks which, on the one hand, permit compliance with regulatory obligations, and on the other, make it possible to identify the critical issues typical of each phase.For this reason, it is necessary to know the core industry standards, know how to interpret diagnostic outcomes and know the possible countermeasures in case of critical issues.

Choice of a new insulating liquid

– Classification IEC 60296
– Corrosiveness surveys
– Role and effects of additives

Supply of a transformer
– Checks suggested during supply
– Heat run and gas tests (DGA)

– Real cases of “infantile” failures

Monitoring during operational life
– From the diagnosis of degradation to corrective actions
– Long-term monitoring: a preventative tool
– Learning from failures
End of life
– Monitoring of thermal degradation (Trend analysis of CO2 and 2-FAL)

Post-failure checks and post-mortem
