Differences ANSI/IEEE and IEC altitude Correction Factors
(OP)
Hello, dear friends
Could you help me whats is differente between ANSI/IEEE and IEC on altitudes Correction Factors ...?
what is a good option to aply on high altitude site, where the dielectric strength is less?
any opinion , information will help..!!
thx

what is the best options up 2000 m ? which standart or other literature coul herlp me to choose the insulator with the better performance at this side?
RE: Differences ANSI/IEEE and IEC altitude Correction Factors
I've always understood IEC to be +1% for every 100m over 1000m. IEEE basically follows the same up to 3000m (I think). Above 3000m it changes slightly.

See the enclosed graph for comparison purposes.
