In SGEM programme this was done to the application area of fault management. In process level the data is needed for fault Clearance purposes. But in enterprice level the same data can be utilized for fault prediction and preventive maintenance purposes. Research pilot results In SGEM programme these data analytics were realized as cloud services. New needs for data utilization and incresing amount of open data sources require technology providers to develop more agile platforms based on cloud technology and service oriented business models. This has been successfully demonstrated within SGEM programme with few target end-user benefits: - Reduce maintenance costs: Auto-generate test reports with available process data. When the protection has been successfully reacting to real network faults, there is no need for additional tests o Predict faults: React to small disturbances before a permanent fault happens. When fault location and correlation to weather data is evaluated already to small disturbances, utility can react before the permanent fault happens. Integration to weather data was implemented in cooperation with the MMEA programme (Measurement, Monitoring and Environmental Assessment). mmea "New services" for business concepts r, r ” r _ _. i . _i_. l' _ , sjIataat-r4:nautrmnrlmrirutrttratt
