Short Circuit Forces

Short Circuit Forces

(OP)
I am currently working on a calculation of short-circuit current forces for a 3-phase horizontal bus system.

I have exhausted my didactic sources and a few online sources looking for the method used to calculate these forces. Is there anyone who can deliver a formula or 2 to help me out?

I don't really want to go all the way back to physics 2 to get the capacitive and inductive forces and use those to find the electrical force. Pardon me if I'm trying to be a bit lazy about it.

IEEE guide for design of substation rigid-bus structures

Abstract
Rigid-bus structures for outdoor and indoor, air-insulated, and alternating-current substations are covered. Portions of this guide are also applicable to strain-bus structures or direct-current substations, or both. Ampacity, radio influence, vibration, and forces due to gravity, wind, fault current, and thermal expansion are considered. Design criteria for conductor and insulator strength calculations are included.

Chapter 6.

This used to be available as a proper book with some fantastic  old photographs, not sure if it is still in print or not. Mine dates from the 1950s.

If we learn from our mistakes I'm getting a great education!

This file is corrupted somehow and I can't download it. I have alerted the site, but do you maybe have a copy you could post or send?
