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
City of Columbus Electric Distribution Digital Conversion Project
• Existing Datasets– AutoCAD drawings– Hand drawn manhole/vault sketches– Access database– GPS points
City of Columbus Electric Distribution Digital Conversion Project
• Existing Datasets: AutoCAD Single Line Drawings (underground)
City of Columbus Electric Distribution Digital Conversion Project
• Existing Datasets: AutoCAD Single Line Drawings (overhead)
City of Columbus Electric Distribution Digital Conversion Project
• Existing Datasets: AutoCAD Detail Drawings (manholes/vaults)
City of Columbus Electric Distribution Digital Conversion Project
• Existing Datasets: AutoCAD Detail Drawings (padmount transformers)

• Existing Datasets: Hand drawn manhole/vault sketches
City of Columbus Electric Distribution Digital Conversion Project
• Goals– Seamless data showing primary distribution
lines– Locations/attributes – Connectivity– Allow for future development / analysis
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
Telvent Multispeak Data Model, ArcFM Software
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
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

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
Data Conversion Strategy
• Create manhole diagrams for Conduit Manager
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
Data Conversion Strategy
• Digitize underground conductors from manhole to manhole – Break, but not
snap at manholes
Data Conversion Strategy
• Add switches and transformers within manholes/vaults– Connect to match
detail drawings– Use ArcFM
favorites for composite features
Data Conversion Strategy
• Associate conductors to ducts in manholes to complete Conduit Manager diagrams
Data Conversion Strategy
• Associate conductors to ducts in manholes– Can split by phase to different ducts
Data Conversion Strategy
• Digitize overhead conductors, transformers– Draw close to, but
don’t snap to poles– Don’t need to
break at poles
Data Conversion Strategy
• Add additional devices on poles– Capacitors
– Switches (section points, tie points, auto-transfer)
– Risers (potheads), circuit feeders
– Regulators
– Reclosers
– Fault Indicators
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
Data Analysis/QC
• ArcFM Electric Traces
Data Analysis/QC
• ArcFM Feeder Manager Locator Tool– Will detect loops, devices energized by more than one
circuit, de-energized devices
