Operating Maps for ITC-Midwest Circuits

Operating Maps for ITC-Midwest Circuits

ITC Holdings

Commonwealth was contracted to create operating maps for approximately 600 individual circuits in the ITC-Midwest transmission system.

To begin the process, ITC staff extracted transmission line information from their current GIS system and delivered them electronically to Commonwealth. Commonwealth CADD operators then placed the extracted information into MicroStation files created using ITC standards, borders, and title blocks.

Construction diagrams and location tables were provided by ITC for reference. Commonwealth placed major highways, street names, and other locational details on the maps. We then identified substations, breakers, taps, and pole-top switches on the newly created drawings.

Additional operating maps were created for “protection zones” in which more than one circuit was included in a map.
