This post has to do with blackburns protective relaying text - 2nd edition...I know you guys have it!
On page 37, 2.4 Blackburn says that:
For either the wye or the delta connection the following basic equations apply;
S3p = sqrt(3)*VLL*IL (VA)... 2.3
VLL = sqrt(3)*VLN<+30... 2.4
IL = S3p/(sqrt(3)*VLL)...2.5
Doesn't 2.4 only apply to wye?
