17. Benefits to Utility

18. Line Patrolling Previous patrolling methods included ♦ Driving by exposed portions of line ♦ Patrolling on foot through woods and mountains Patrolling efforts significantly reduced with communicated data Time to repair system decreased Safety for Central Lincoln PUD personnel increased

19. Easy Integration Equipment was carefully selected for use with existing infrastructure Equipment has multiple purposes ♦ Saves training time ♦ Reduces cost of operation and installation ♦ Reduces hardware bloat Equipment provides unforeseen benefits from robust data pool

20. Current and Thermal Reports Thermal and current loading can be used for long-range planning of switching and of circuit construction requirements

21. Future Endeavors Powerful hardware ♦ Allows for future growth of system ♦ Provides critical data for automating transfer schemes New uses for data are possible, building on load planning use case

22. Lessons Learned Planning, planning, planning Location choice Testing procedures Data integration

23. Lessons Learned Location is critical to ensure cost-effective use of hardware and to reduce risk to Central Lincoln PUD patrol crews Mesh repeater location is important to ensure signal propagation through rough terrain Power output from FCI radios dictates where repeaters are required

24. Bench Testing Test each measurement device and system as a whole to make sure full integration is achieved Test multiple measurement devices at once Test partial and full signal blocking on radio network side to better understand all possible system fault conditions

25. Conclusion Adding communications capabilities has enhanced system operation needs and improved safety Carefully selected equipment has paid dividends in regard to system capability and growth potential
