How to calculate kva? what is the formula...

Answer / benji

KVA= (V*I)/1000 (for single phase)
= 1.732(V*I)/1000 (for three phase)
= KW/p.f.

Is This Answer Correct ?    3 Yes 0 No

How to calculate kva? what is the formula...

Answer / sks

KW 3 ph = 1.732 x line voltage [AVG of sum] x line current[
AVG of sum] x P.F.
EXAMPLE 320 KVA GENSET= 1.732 X V 415 X 445
EXAMPLE 256 KW GENSET = 1.732 X V 415 X 445 X.8

Is This Answer Correct ?    4 Yes 2 No

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?
