Feeder Separation Project
- 1. An Economical and Efficient Approach to Electrical Survey Data and Creation of Topology
- 2. Scope of work • GIS Survey(Support). • Export of survey data to NA tool • Network Analysis • BOQ Generation and approval
- 3. Offerings • Topo Bridge Tab for survey • Data Conversion Service • Network Analysis Service • Topo Bridge NA for Network Analysis
- 4. GIS Survey • Survey of HT • Survey of DT • Survey of LT • Survey of CI • Marking of Poles • Excel preparation
- 5. Data Export and NA 1. Preparation of Network model for Network analysis software 2. Existing Analysis and proposal Analysis 3. BOQ and Proposal AUTOCAD Diagrams preparation.
- 6. Preparation Network model for Network analysis software • Checking of GIS Survey of HT, LT, DT, and CI for Data Anamolies. • Preparation of topology from GIS Survey data using “TOPOBRIDGE”. • Checking for Disconnections and Long lines. • Extraction of Topology data into Network Analysis Software’s like Cymdist/Neplan/etc through “TOPOBRIDGE”. • Preparation of DTR wise Loading data and Loading percentage according to AG, DOM Loads through “TOPOBRIDGE”.
- 7. Existing Analysis and proposal Analysis • Performing Existing analysis and calculating Technical Losses • Calculation including LT network for Existing Feeder and preparation of its analysis report which includes • DT Loading profile. • Feeder wise Analysis. • Technical Loss report • Proposal Analysis for separation of AG and NON- AG Loads.
- 8. BOQ and Proposal’s AUTOCAD Diagrams preparation. • Creation of Existing and proposed full HT Diagrams • Creation of Individual and Proposed DTR diagrams • Digitization of SOI Map. • Preparation of BOQ
- 9. Inputs required: Survey Data of LT HT DT CI SOI MAPS Analysis Report Templates(optional) Autocad templates(optional) BOQ Template(optional)
- 10. Sample Project Plan Assuming a feeder with following particulars •Length of Feeder: 30kM •No of HT poles: 155 •No of DT: 20 •No of LT poles: 300 •No of CI:1200

- 15. Man day savings for 100 similar feeders
- 16. Financial savings for 100 similar feeders
- 17. Project plan for 100 feeders Perticulars Target No of feeders 100 Team size 4 No of days required 180 No of teams required 8 No of “Topo Bridge tab” required 16 Analysis team required 4 No of feeders can be completed/month 16
- 18. Deliverables • Network GIS Shape Files • NA software (Cymdist, Neplan like) compliant files • DTR wise List • Existing Analysis Report for technical Losses • DTR Loading profile • Feeder Technical Loss report • Listing of Overloaded transformers and overloading conductors • DTR-Wise Technical parameters comparison List(After and Before {Feeder Separation}). • PDF’s of all the DT & downstream LT Networks whose network was subjected for change in the proposal analysis (Existing DT & LT Network Diagrams). • Full HT Network which includes HT points, HT Lines, DT’s of Existing network. • Full HT Network which includes proposed HT points, HT Lines and DT’s. • BOQ • Digitized SOI Map. (All deliverables are soft copies only)
