Client-side computation
All calculations run locally in your browser—fast iteration, no server dependencies, and offline-capable after first load.
Sag & Tension Tool
Browser-based calculations for conductor sag and tension across predefined load cases—with exportable results and transparent assumptions. Built on the ruling span method.
Engineering tools
Purpose-built tools for overhead line design—from initial sag calculations to stringing, clearance verification, and EMF field modeling.
Sag & Tension Calculator
Calculate conductor sag, tension, and catenary parameters across all predefined load cases. The primary tool for span analysis.
Stringing Tables
Generate sag tables across temperature and span ranges for general or span-specific stringing scenarios.
Insulator swing & tensile strength
Analyze insulator swing angles and ultimate tensile strength checks for suspension and tension insulators under load cases.
Line Clearance
Define load cases, compute minimum distances, and visualize clearance diagrams for conductors.
Batch Calculations
Run sag, line-clearance, tension, and insulator swing calculations across multiple towers and spans in a single batch workflow.
Magnetic field
Model conductors and compute magnetic flux density, Presentation of results by iso-contours, and plots from saved datasets. Optimize fields by best and worst cases.
Electric field
Electrostatic potential and electric-field magnitude from conductor geometry and voltages; plots, iso maps, and audible-noise estimates.
Substation
Substation oriented workflows with tools for calculation short-cicruit effects, thermal dimensioning and load-calculations.
Custom Lines
Manage your conductor catalog. Import and export line data using the .lin format.
Standards-aligned
Preset load cases follow SS-EN 50341-2-18 (Swedish NNA). User-defined cases allow custom temperature, wind, and ice inputs.
Export & share
Download results as CSV or PDF with full metadata and timestamps. Share conductor catalogs via .lin files.
