Ok... maybe my post is not very clear... (I'm new) So I'll write you down the classic equation for a conductor fault current forces. It's taken from the IEEE Std 605.
For Metric units:
Fsc=(1.6*(r)*Isc^2)/((10^4)*(D))
For Imperial units:
Fsc=(43.2*(r)*Isc^2)/((10^7)*(D))
Where
Fsc=Fault...
Hi!
I'm searching the equation for the short-circuit force on a substation busbar. I already find the equation in the IEEE Std 106-1998 (on page 16) (IEEE Guide for Design of Substation Rigid-Bus Structures) and I don't understand where does the constant (see Table 2), used in the equation...
