Unbalanced fault formula

[roy167]

I took this from Engproguide cheat sheet. I don't think this is correct. According to me , for phase A to B fault, it should be. 

IA = -IB

IC=0

vA=VB


Line (Phase A) to Line (Phase B) Fault

VB=VC​

IB=-IC​

IA=0​

IA0=0;IA1=-IA2=EAjX1+jX2​

IB=IA1*(a2-a)​

You are right. The formulas are for B-C line -line fault.

I belive Justin posted his latest cheat sheet in on of the forum topics, i believe that is updated
