Thanks,
But I'm away from the utility, and difficult to cantact them.
I'm doing voltage and frequency dynamic study.
Can you guide me who is the expert (eng-tip member) for this study in this website.
I'm doing a dynamic study for a utility. I'm facing following obstaches. If you have any idea kindly help me.
(1) If I know the positive sequence impedance of a tranmission lines and transformers, how I can find out and calculate the zero sequence impedance for both: lines and transformers...
