  1. Establishing an Electric Distribution GIS Using ArcFM Melissa A. Williams, P.E. Senior Project Engineer Stantec Consulting September 29 - 30, 2011 | Hyatt Regency Hotel | Columbus, Ohio

  2. Establishing an Electric Distribution GIS Using ArcFM • City of Columbus Electric Distribution Digital Conversion Project • Telvent Multispeak Data Model, ArcFM Software • Data Conversion Strategy • Data Analysis/QC

  3. City of Columbus Electric Distribution Digital Conversion Project • Existing Datasets • AutoCAD drawings • Hand drawn manhole/vault sketches • Access database • GPS points

  4. City of Columbus Electric Distribution Digital Conversion Project • Existing Datasets: AutoCAD Single Line Drawings (underground)

  5. City of Columbus Electric Distribution Digital Conversion Project • Existing Datasets: AutoCAD Single Line Drawings (overhead)

  6. City of Columbus Electric Distribution Digital Conversion Project • Existing Datasets: AutoCAD Detail Drawings (manholes/vaults)

  7. City of Columbus Electric Distribution Digital Conversion Project • Existing Datasets: AutoCAD Detail Drawings (padmount transformers)

  8. City of Columbus Electric Distribution Digital Conversion Project • Existing Datasets: Hand drawn manhole/vault sketches

  9. City of Columbus Electric Distribution Digital Conversion Project • Goals • Seamless data showing primary distribution lines • Locations/attributes • Connectivity • Allow for future development / analysis

  10. Telvent Multispeak Data Model, ArcFM Software • Data Model created/maintained by Telvent GIS (formerly Telvent Miner & Miner) • M&M provided electrical engineering services since 1946 • Automated Mapping/Facilities Management/GIS since 1986 • Business partner with ESRI • Telvent ArcFM Enterprise GIS is an extension for ArcGIS

  11. Telvent Multispeak Data Model, ArcFM Software

  12. Telvent Multispeak Data Model, ArcFM Software • Customization of data model: • Used Microsoft Visio to make changes to data model • Added / Changed / Deleted attributes to match existing Access database fields • Added / Edited domains, subtypes

  13. Telvent Multispeak Data Model, ArcFM Software • Advantages of using ArcFM software (vs data model alone) • Ability to perform more complex analyses and better QC (e.g. electric traces) • Additional functionality through other Telvent solutions • Conduit Manager • Responder

  14. Telvent Multispeak Data Model, ArcFM Software • Conduit Manager

  15. Telvent Multispeak Data Model, ArcFM Software • Responder

  16. Data Conversion Strategy • No heads-up digitizing with georeferenced images • Start with GPS’ed and ortho-verfied point features • GPS points for poles, manholes/vaults • Ortho-verified padmount transformers

  17. Data Conversion Strategy • Create manhole diagrams for Conduit Manager

  18. Data Conversion Strategy • Digitize conduits between manholes/vaults • One conduit per duct bank • Split conduit if different configuration on each end • Snap to manhole/vault points

  19. Data Conversion Strategy • Digitize underground conductors from manhole to manhole • Break, but not snap at manholes

  20. Data Conversion Strategy • Add switches and transformers within manholes/vaults • Connect to match detail drawings • Use ArcFM favorites for composite features

  21. Data Conversion Strategy • Associate conductors to ducts in manholes to complete Conduit Manager diagrams

  22. Data Conversion Strategy • Associate conductors to ducts in manholes • Can split by phase to different ducts

  23. Data Conversion Strategy • Digitize overhead conductors, transformers • Draw close to, but don’t snap to poles • Don’t need to break at poles

  24. Data Conversion Strategy • Add additional devices on poles • Capacitors • Switches (section points, tie points, auto-transfer) • Risers (potheads), circuit feeders • Regulators • Reclosers • Fault Indicators

  25. Data Analysis/QC • ArcFM Electric Traces • FeederID attribute populated for energized conductors/devices • Can trace by phase • Can open/close switches to see new circuit path

  26. Data Analysis/QC • ArcFM Electric Traces

  27. Data Analysis/QC • ArcFM Feeder Manager Locator Tool • Will detect loops, devices energized by more than one circuit, de-energized devices
