An Economical and Efficient Approach to Electrical Survey Data and Creation

of Topology

Scope of work

• GIS Survey(Support).

• Export of survey data to NA tool

• Network Analysis

• BOQ Generation and approval

Offerings

• Topo Bridge Tab for survey

• Data Conversion Service

• Network Analysis Service

• Topo Bridge NA for Network Analysis

GIS Survey

• Survey of HT

• Survey of DT

• Survey of LT

• Survey of CI

• Marking of Poles

• Excel preparation

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.

 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”.

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.

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

Inputs required:

Survey Data of  LT HT DT CI 

SOI MAPSAnalysis Report Templates(optional)Autocad templates(optional)BOQ Template(optional)

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
