MeteorSpec LT is freeware toolkit for electrical designers and consists of the following components: MeteorSpec-NETWORK: Software for simulation, analysis and calculation of 0.4kV distribution networks; MeteorSpec-ELECTRIC: Collection of various calculators for electrical designers and students; MeteorSpec-PLINE: Totally customizable multipurpose tool for summarizing lengths and areas of any objects that can be modeled by lightweight polylines. The MeteorSpec LT works in all versions of GstarCAD 2015-2020 (excepting GstarCAD Light).

The software fully automates all electrotechnical calculations and computations of specifications in low-voltage distribution networks. Easily accessible calculators for electricians significantly speed up your work.

Component MeteorSpec-NETWORK


• Support for low-voltage networks with a radial topology of any level of complexity;

• Calculation of short-circuit currents according to IEC60909 (last edition 2016);

• Calculation of voltage losses in low-voltage feeders with a balanced load;

• Calculation of power sum and actual load currents in low-voltage feeders;

• Adjustable cable database according to regional standards;

• Automated computation of cable specifications;

Electrotechnical calculations in 0.4kV distribution networks


The program has 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.

You can perform calculations of SC-currents, voltage losses, power sum and actual load currents in low-voltage feeders at any node and in any cable section of low-voltage feeders.

Specifications of equipment


The MeteorSpec-NETWORK allows you to quickly obtain the cable specifications of network models. Results of the specification are output into the drawing in a form of a table. Just specify the starting point of the table.

Connection with street lighting networks


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 partner software named MeteorCalc SL.

You can find more information about the MeteorCalc on the website:

Compatibility and localization


The MeteorSpec-NETWORK 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.

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

Component MeteorSpec-ELECTRIC


The MeteorSpec-ELECTRIC is collection of various calculators for electrical designers and students.

The current version of the MeteorSpec-ELECTRIC contains the following calculators:

• Current carrying capacity calculator – calculation of continuous current-carrying capacity of multi-core power cables;

• Power -> Current calculator – calculation of currents in three-phase, single-phase and DC elecrtical circuits;

• Current -> Power calculator – calculation of active and reactive power in three-phase, single-phase and DC elecrtical circuits; • Ohm’s Law calculator – calculation of voltage, currents and resistance in DC elecrtical circuits;

We’ll supplement this collection at the request of the users.

Component MeteorSpec-PLINE


This “time-tested” plugin is what earlier used to be the main part of the MeteorSpec software. The MeteorSpec-PLINE allows to calculate summarized lengths or/and areas of any objects that can be modeled by lightweight polylines.

Thousands of users use this plugin to calculate bills of materials for communication cables, computer networks, pipes, pavements, fences, curbs, protective coatings etc.

The MeteorSpec-PLINE flexibly adjusts to any units of measurement and it has the totally customizable Data Library. The user can pre-define any data of equipment necessary for work, according to the needs and tasks to be solved by the user.

We wish you productive work with the MeteorSpec LT!
