Sbase = Pbase in p.u values?
Sbase = Pbase in p.u values?
(OP)
Hello,
I am reading something about per unit values and the text seems ok:
Zpu = Z(actual)/Zbase, Ipu = I(actual)/Ibase
but then they say: P(base) = S(base)
Shouldn't P(base)=S(base)*cos(Phi)?
(the material is from an ebook written using Mathcad).
Thanks.

If it makes you feel better, choose Phi =0, cos(Phi)=1.
