GElectrical is a free and opensource electrical system analysis software for LV/MV electrical distribution networks. Following features are currently implemented.

• Schematic capture.
• Pandapower network generation from schematic.
• Power flow time series analysis (Symmetric and Assymetric).
• Power flow with diversity factors (Symmetric and Assymetric).
• Voltage drop analysis.
• Short circuit analysis (Symmetric and SLG).
• Coordination analysis for power supply protection devices with support for CB and fuse protection curves; damage curves for transformers, cables and motors.
• Support for daily load curves for load elements.
• Support for arriving network parameters for custom geometry OH lines.
• Support for modeling networks with mixed TN-S/ TN-C/ TT/ IT earthing systems.
• Electrical rules check for checking conformity with IEC/ local electrical guidelines.
• Print and export of drawings to pdf.
• Generation of analysis reports.

GElectrical uses pandapower as the backend for implementing power flow related functionality like voltage drop and short circuit analysis.

Please note that the program is in active development and bugs are expected. Cross checking of generated calculations is reccomended. See Roadmap for current limitations.

Sample project file

Application can be installed for use on your OS as described below.

It is reccomended to install osifont for schematic capture. This can be downloaded from https://github.com/hikikomori82/osifont/blob/master/osifont.ttf.

Use .EXE installation package available under the latest Release.

Application is published on Flathub repository at GElectrical.

It should be possible to install the application using the default package manager on most linux systems if flathub is setup. Please see https://flatpak.org/setup/ to setup flahub for your linux distribution.
