- 3. Asset Management Investment Key Drivers Asset Management Objectives: • Maximize asset utilization and lifetime, manage risks • Timely maintenance and upgrades to meet demand and avoid outages driven by equipment failures Key Drivers: • Reduce catastrophic events • Maximize network performance and increase efficiency • Reduce unplanned and planned outage costs • Reduce truck rolls • Condition-based rather than time-based maintenance • Improved safety 3

- 5. North America Use Case Trends Predictive Maintenance Substation Monitoring Cap Bank Monitoring 5
- 6. Preventative Maintenance Use waveforms to prevent outages and respond to problems: • Vegetation growth • Failing underground cables – 10 customer complaints of blinks over 2 months 3 troubleman visits, no problem found UG cable subsequently failed, 17 customers affected – 6 fault current events logged. Could be leveraged to characterize and troubleshoot root cause of complaints Example of waveforms from failing underground cable 6
- 7. Preventative Maintenance Multiple fault current events in short period of time - predictors of potential faults and outages: • Animal Contact – Three 4kA fault current events over 2 weeks at same location – Transformer fuse subsequently blew due to animal contact – 38 customers interrupted Example of animal contact at transformer 7
- 8. Substation Monitoring • Identify & prevent transformer and circuit overloads • Correct phase imbalance • Improve planning with historical load profile data • Eliminate truck rolls to read load at substations • Record fault current events – leading indicators of failure 8
- 9. Substation Monitoring • Smart grid sensors & data analytics – Cost-effective alternative to traditional SCADA solutions – Substation transformer loading – Loading per circuit and per phase – Nameplate overload event logging and alarming 9
- 10. Load Monitoring & Switching • Load Switching – Better Visibility & Confidence Problem: – Tie points are often smaller gauge conductors without monitoring – Transfer studies needed to determine risk of switching operation – Without monitoring: • Conservative estimates based on limited data Solution: – With cost-effective smart grid sensor monitoring & reports: • Accurate real-time and historical data • Improved confidence in approved switching orders 10
- 11. Capacitor Bank Issues • Blown fuses go undetected for months or years • Tremendous O&M expense to perform periodic inspections • Installing a SCADA enabled capacitor controller is a large undertaking and expensive 11
- 12. Capacitor Bank Monitoring Inductively powered sensors can alert utility in less than an hour when there is a blown fuse – tremendous savings to O&M budget 12
- 13. Key Considerations to Evaluate Sensors “From an asset manager’s perspective, this technology will allow us to know immediately if there is a problem that is easy to fix or if it is a serious problem that requires capital investment.” -- Ivano Laboricca, Vice President of Asset Management Toronto Hydro 13
- 14. Key Considerations to Evaluate Sensors • Ease of deployment: – Weight, ease of install with hot stick – Need for pole-mounted equipment, cabling, and 120V secondary power • How is it powered and maintained: – Inductively, batteries, solar panels? – Remote configuration, firmware upgrades, and administrative management tools • Communications options: – Cellular, wireless mesh, 3rd party radios/modems • Data accuracy: – Does it have a pre-packaged analytics package to filter out false-positives? • Scalability: – When thousands are deployed, will the architecture of the platform scale? • Ease of integration into SCADA, Historian, and DMS: – Has the sensor vendor been able to integrate with back-office systems? How long did integration take? 14
