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)

• 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

• 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
