9)Calculation stresses created by short circuit force

1) Stresses because of s/c forces between Phase conductors





Where, z = section modulus

= 0.167*d2* b for horizontal orientation
=0.167 n* d* b2 for vertical orientation

2) Stresses because of s/c forces between sub-conductors




Where, zs =0.167d2 b


Total stress on busbar conductors

TOTAL = Stresses because of s/c forces between Phase conductors + Stresses because of s/c forces between sub-conductors
