Extended list of standard types

[DavidEnergie]

Does anyone have and is willing to share a list of standard types that goes beyond the ones available in net.std_types?

I am currently modelling some less common nominal voltages (such as 30 kV) and transformer types (e.g. YNyn) and am wondering about existing work to rely on but also to help building.

Any pointers are very welcome.
Cheers
