Hello. I tried installing GElectrical on my RPi4 from Snap. It looks great but I'm struggling with making a schematic easily. Once I have placed an element (grid, busbar, load) on the sheet I cannot move it. So once it is initially placed then it is stuck in that position forever. I don't know if this is the expected behaviour, whether I'm doing something wrong or if it is an issue specific to the RPi4 installation?

Thanks for your help (and keep up the development!)

Hi,

It would be great if you could add a shunt reactor and a three winding transformer.

Functionality

• Associative property/ let through energy calculations.
• Coordination analysis tools for marking critical points.
• OLTC controller for power flow (Time series).
• OLTC controller for 3 phase power flow (Time series).
• Powerflow simulation with diversity factors.
• 3 ph Powerflow simulation with diversity factors.
• OLTC controller for power flow.
• OLTC controller for 3 phase power flow.
• Handling of distributed neutral.
• Handling of TT & IT earthing systems.
• Tooltips/ documentation for element field values.
• Documentation for application.

Reliability

• Tests for checking calculation correctness with reference.

New elements

• Changeover switch
• Generator (support for 3 phase power flow)
• Impedance (support for 3 phase power flow)
• Shunt capacitor (support for 3 phase power flow)

Generators do not Cycle port.
I am doing something wrong or it is not implemented.
thank you.

Just stumbled across this app, looks very cool! I'm curious though why it's using GTK3 even though it seems to be quite new. Do you have plans to port to GTK4? Are there any blockers from the platform side?

Hi, I installed GElectrical on RPi4 using Snap. I can create schematics and I can export files (network.json, report.pdf, network.html etc) successfully. But when I try and save a project nothing happens.

I tried to run the application from a Terminal (rather than the drop down start menu) to see if made any difference. I still have the same issue but in this case I can see some error messages that might help diagnose -

The first warning (mkdir) is when the program starts. The second warning (GtK) is when I try to save the project.

Do you have any idea what I can do to make it save correctly?

Thanks for your help. Ben

Hello Manu.
I'm testing electrical.
I cannot set the values of the elements, I get a forbidden signal.
Regards, thank you.

Working in dark mode is very difficult, the colours don't contrast well.

The ability to export selected part as png would be very appreciated

I follow the steps you mentioned for Windows installation, still, I got the below error
Traceback (most recent call last):
File "gelectrical_launcher.py", line 27, in

File "C:\Users\BATMAN1\AppData\Local\Programs\Python\Python38\lib\site-packages\gi_init_.py", line 47, in
from . import _gi
ImportError: DLL load failed while importing _gi: The specified module could not be found.

what should I do?
