Hi, I have problem of converge in a syncronous machine when I add a voltage source with impedance, that represent a external grid. When add a external grid the syncronous generator did not converge, but when the external grid is exclude there is no more converge problem. Help pliss.

How to model a concrete pole (14m) for a distribution line?

I am doing a study on the lightning performance of a 33kV distribution line. I have watched videos but they are all based on transmission lines. I would like to know how to model a concrete pole 14m in length. I have been able to model the insulators, conductors, earth wire, and surge arresters

Non-Linear Inductance on Delta winding connection

I want to adapt the example present in ~EMTPWorks\Examples\ApplicationCases\Transformer_data\TestExample\TransformerModel in the case of a magnetizing branch connected in the delta connection of the transformer (tertiary side).

The "L nonlinear" block is used to convert the I-V curve to I-phi curve.

1) However, I do not know if I have to use the phase-to-ground voltage for the base (as in the example) or the phase-to-phase voltage.

Hello dear team, I have a query, when modeling with the data line/cable subroutine with a PI model and I load it into an FD type line, it gives me an error indicating error in the FDLine device and error in the model data or file not found.

Low-severity error has been dectected.

I'm getting an Internal Error when launching EMTPWorks version 4.2.1: A low-severity error has been detected, code 285210. Serious data corruption is unlikely, but the operation may not have completed successfully. If the message is serious fine, I would like to suppress for end users so they don't panic.

Hi i'm trying to use the "LFdataLoad" method to load the load flow results to the synchonous machine in my script but i don't know the exact syntax.

Thanks
