What do you mean by pf of a generator? Power factor purely
depends on the load (wether inductive, reactive or unity)
then what does the pf mentioned on the generator nameplate
means?

Answer Posted / balajieee
power factor is the cos angle between voltage¤t.using
that nameplate pf value u can find kw capacity of a
generator for its kva rating(formula,p=sqrt3*v*i*cospi.).if
you are connecting pure resistive load means power factor
is unity,so the pf of generator will incrase from its name
plate value.capacitive load also incrase the pf of
generator.inductive load will decrease pf value.so the
average of resistive,inductive,capacitiveload pf ,name
plate pf will give final output pf of generator.

Dear all, I just want to ask an expert on this forum for some insights. For the magnetic balance test, when applied voltage on a Delta-Star transformer e.g. Dyn11, the following relationships apply for HV side: 1. H1-H2 = H2-H3 H3-H1 2. H2-H3 = H3-H1 H1-H2 3. H3-H1 = H1-H2 H2-H3 For the LV side also: 4. X1-X0 = X2-X0 X3-X0 5. X2-X0 = X3-X0 X1-X0 6. X3-X0 = X1-X0 X2-X0 Is there a similar pattern for Y-d, Y-Y, D-d? And how about Y-z, D-z, Z-y transformers? I've tested a YNzn5 transformer and for LV side I don't see the pattern. In this particular case I got for LV side the following (see values below): H1-H0 H2-H0 H3-H0 X0-X1 X0-X2 X0-X3 128.0 119.9 7.2 29.2 13.3 15.8 70.7 128.4 59.2 23.4 22.0 3.6 7.2 120.1 128.1 13.4 29.3 15.8 What is the relationship here for LV? For row 1 I see the relationship, for row 3 I also see but it's shifted, but for row 2 I don't see such relationship. Any suggestions, answers, someone?
