What formula are you using for slip?

There was a copy of Wildi’s book at my work!!!  I’m excited! 💃

Actually now that I think about it, in the second problem , the sqrt3 cancels out. V1/v2 = i2/i1 for the wye vline = vphase * sqrt3 and for the delta I_line = I_phase * sqrt3 

I can follow Graffeo’s example 26.  The problem asks you to find turns ratio given primary voltage and secondary voltage.  It says to divide the wye side voltage by sqrt3  to get phase voltage before calculating the ratio. However the next problem is very similar, but it seems the delta wye is...

Really appreciate it!

I did all the ncees practice exam problems and most of graffeo.  Someone gave me the Handbook by Beaty, but I’m thinking of buying complex imaginary next.  Any advice on which one to tackle next?

I’m all signed up 😁

I hope It doesn’t take long for them to verify my fe
