Asset health index and condition estimation• Health indices in use for transformers & substations since 2012 • Used to identify the possible asset risk related to older substations

• Maintenance and refurbishments optimaization• Analysis can strengthen already known component weaknesses but may

also point out additional needs for further clarification

Power Transformer health index• Based on Dissolved Gas Analysis (DGA)

+ oil quality, tan δ, oil temperature

• DGA finger prints and a fault library are very useful in defect investigations

Transformer fault - Nurmijärvi PM1Increasing oil gas ratio was noticed and taken under observation in May 2012. Strong correlation between Low Voltage side current and oil gas ratio was detected by Condition Monitoring System and confirmed with diagnostics measurements. The early notice gave time to react and remedial actions were launched in time.

SF6 leaks - saving both nature and money• Several Circuit Breaker SF6 gas leaks and detector failures has been detected at early

stage by monitoring and automatic notifications.

Benefits and future• Health indices are used for long term planning

• On-line maintenenace monitoring helps to catch faults before they cause problems for the control room

• OSIsoft PI enables us to get SCADA measurement information to the use for asset and maintenance engineers

• Next steps• Health index for protection assets• Elvis Maximo asset ID also in use in SCADA
