MeteorCalc SL

Digitally signed app



MeteorCalc SL is a powerful CAD plugin for designing electrical parts of outdoor lighting networks such as street lighting and tunnel lighting installations. 


The main features of MeteorCalc SL are:


  • Calculation of short-circuit currents according to IEC60909 (last edition 2016); 
  • Calculation of voltage losses in street lighting feeders with an unbalanced load; 
  • Calculation of power sum and load currents in street lighting feeders and distribution panel boards; 
  • Automated computation of specifications and explications of equipment; 
  • Automated drawing of single-line schemes of street lighting feeders.  
  • New package of 3D commands let you create 3D visualization models of simulated street lighting networks.
  • New 3D block constructor allows you to quickly create realistic 3D blocks of street lighting objects.

Electrotechnical calculations

The program has a calculation process, which is open to monitoring. Every step of all the electrical calculations (including interim and auxiliary results) can be thoroughly checked on the user request. 

Build-in Help system contains detailed descriptions of all calculation procedures and recommendations for the selection of protective devices in street lighting feeders.


Specifications of equipment

The following specifications are available: street lighting poles, pole foundations, luminaries, power cables, cable tracks, earthing devices, electrical equipment and internal wiring.

External reports with results of specifications and explications can be exported to an external spreadsheet application.  


Street lighting models and schemes

The MeteorCalc SL enables the creation of street lighting network models of any level of complexity. There are no restrictions on the number of branches in street lighting feeders. 

Drawing accurate and detailed schemes of street lighting feeders is very simple with the MeteorCalc SL. Single-line schemes will be drawn automatically from a feeder start point to each selected endpoint.


Data libraries 

There is a built-in database of cables used in the networks of street lighting. We permanently expand the cable database and we’ll add new cable types according to customer requests. 

A customizable Data Library for street lighting units (with luminaires, street lighting poles and foundations) is intended for repeated use in your projects. 


Compatibility and localization

MeteorCalc SL has localized versions for different regions because there are different types of power cables and different electrotechnical calculation settings in various countries. 

Just tell us, where are you from, and we will make and provide a corresponding regional version to you.

MeteorCalc SL supports the 230/400V (TN) 50Hz voltage systems in street lighting networks and the Metric system of units in dwg-files. The nominal voltage is adjustable within 220/380V - 250/440V according to regional standards.


Connection with low-voltage distribution networks

There is the partner software named MeteorSpec LT. Any junction of low-voltage network simulated by the MeteorSpec-NETWORK can be used as a power supply point of a street lighting cabinet designed by the MeteorCalc SL.

You can find more information about the MeteorSpec LT on the website:

체험판 설명

Trial version

The fully functional 30-day trial version has only one restriction: the number of street lighting unit blocks in a dwg-file should not exceed 50 pcs.

For first start we recommend you refer to the Getting Started (Beginners Guide) brochure and use the MeteorCalc_SL_Example_1_Street_Lighting.dwg file. This step by step example is adapted for the trial version. 

The trial version has the cable database, which is intended for demonstration and evaluation purposes only. Please, contact us, and we'll add all the necessary cable types for your location.
