RE: Short circuit forces

Hi,

You can find something about short cct forces calculation in CEI IEC 865 standard. IEC 865-1 gives the way of calculation but IEC 865-2 have example calculation which is very helpfull.

RE: Short circuit forces

This question sounds familiar.  Have you searched the site for this topic?  I seem to recall a similar thread earlier this year.  While it is quite common in substations, I have never designed a transmission structure for short circuit forces.

RUS Bulletin 1724E-300, available at  http://www.usda.gov/rus/electric/bulletins.htm
discusses design of rigid bus for short-circuit forces.  In short, the force is a function of the current squared divided by the distance between the phases.
