Hi all engineers,

I would like to ask lightning protection for substation, normally you guys design this protection using "fixed angle" method or using "EMG - Rolling Sphere" method ?

If any engineers here practice the method of Rolling Sphere, may I know how you guys find the surge impedance in the section of transformer bay where as there is no conductor installed on it. or I may still not understand clearly the term conductor in the formula.

All I mentioned above from IEEE Std 996-1996.

Regards,
Linspire
