GeoEner Proje Analiz
Reads overhead line projects from their drawings and produces engineering results: profile, sag, ground clearance and crossing checks, pole and cross-arm suitability, mechanical and electrical calculations and grounding; with single-line diagrams and longest LV path analysis, drawing sheets and deliverables come from one place.
About the Product
GeoEner Project Analysis brings together the screens where a line project's drawing is read and engineering results are produced. It uses the preliminary project or as-built and site handover drawing version in GeoEner as input; the main line and branches are defined on the map, and a field survey file is loaded so terrain, side profiles and obstacles are taken into account.
In the Route Workspace, the profile is drawn at sheet scale, with the conductor curve, ground clearance violations and uplift points marked on it. The sag table is calculated per tension section using the change-of-state equation and catenary solution. The minimum conductor-to-ground distance is checked per span, and vertical and horizontal distances at road, railway, power line and pipeline crossings are checked by crossing type. Pole top force, cross-arm suitability and TEDAŞ tolerances are checked, with ice zones taken from TEDAŞ's district list. Voltage drop, loading and losses are calculated, and step and touch voltages are checked for kiosk and pole grounding. Every result is shown with the assumptions it rests on.
The Single-Line Diagram generates the feeder tree from a substation automatically from network data and shows voltage drop and loading in color bands, together with short-circuit values. Longest LV Path finds the longest feeding path in each transformer area. Profile, pole, sag and clearance sheets come out as PDF, and deliverables such as the sag table, pole list, coordinate list, KML and DXF drawings come in a single ZIP package.
Key Features
A preliminary project or as-built/handover drawing version is chosen as the source, and the main line and branches are defined by clicking poles on the map. Terrain, side profiles and obstacles load from a field survey file, pole elevations from a point list, and study points can be entered by hand.
drawing · field survey · studyThe profile is drawn at sheet scale between 1:2000 and 1:500, aligned with the bottom ruler. The conductor curve, ground contact curve, clearance violations and uplift points are marked, and the view exports as PNG and SVG.
long section · sheet scaleSag is calculated per tension section with the change-of-state equation and catenary solution, with dead-end poles splitting sections. Uplift and conductor breakage are checked, and the maximum sag temperature is configurable.
change of state · catenaryThe minimum conductor-to-ground distance in each span is compared with the acceptance limit. Vertical and horizontal distances at road, railway, power line and pipeline crossings are checked by type, with the crossed line's conductor height corrected for temperature. Building intersections are listed separately.
clearance · crossingsThe pole table shows top force and the governing tension scenario, and cross-arm suitability is checked with suggestions. TEDAŞ tolerances apply, ice zones come from TEDAŞ's district list, and spans in coastal districts are checked with a reduction.
top force · cross-arm · ice zoneVoltage drop, loading and losses are calculated. Grounding is calculated for kiosks, MV poles and LV end poles, step and touch voltages are checked against the grounding regulation, and an Excel report is produced.
voltage drop · groundingThe feeder tree from a substation is generated automatically from network data, showing voltage drop and loading in color bands with short-circuit values, and exports as PNG, SVG or vector PDF. Longest LV Path shows each transformer area's longest feeding path on the map; both refresh every night.
feeder tree · short circuitProfile, pole table, sag table and clearance sheets are produced as PDF. The sag table, pole distribution list, coordinate list, Form-2, route KML, profile and site plan DXFs, quantity take-offs and the study sketch download individually or as a single ZIP delivery package.

How It Works
- 01Select — drawing version
A preliminary project or as-built/handover version is selected, and the main line and branches are defined on the map.
- 02Load — field survey
The field survey and point list are loaded, study points entered, and ice zone and wind conditions set.
- 03Calculate — engineering tabs
Profile, sag, clearance, crossing, pole, mechanical, electrical and grounding calculations run on the same inputs.
- 04Review — violations and assumptions
Clearance violations, uplift and tolerance breaches are flagged, and every result is shown with its assumptions.
- 05Deliver — sheets and package
PDF sheets and DXF, KML and Excel deliverables download individually or in a single ZIP package.
Who It's For
Produce sag, clearance, pole and grounding calculations for line projects directly from the drawing.
Check contractor projects with the same engines, with violations and assumptions on one screen.
Track voltage drop and feeding paths on the existing network with single-line diagrams and longest LV path analysis.
Roadmap
Placing poles automatically along a route using high-resolution terrain data.
Running the analysis directly on the existing network inventory instead of a drawing.

- The same data shared across investment, maintenance and analysis
A platform that digitalizes asset, investment and maintenance management end-to-end for electricity distribution and energy companies, with geographic information system (GIS) support.
A queryable, simulatable copy of your distribution grid: poles, transformers and conductors appear in 3D on real terrain; inventory, maintenance and measurement data come together on a single asset card; health scores, outage impact, load flow and investment scenarios run on the same platform.
Monitor your distribution grid in real time; manage alarms, loading and regulatory risk from a single operator console. The operations module of the GEOENER platform.
Turns investment, project, maintenance and service quality data into management indicators from inside GeoEner, with no separate BI tool: a role-based overview dashboard, an 8-KPI benchmark including SAIDI/SAIFI, notifications on threshold breaches and a summary email every morning.
