Answer / suantak

The inductive reactance offered by an inductor or coil is
null when a dc current pass through it. The reactance
offered by the armature of dc machine is zero, considering
an ideal dc current withough harmonics (in fact a small
amount of reactance will exist due to harmonics).

This is may be the reason why armature inductance is
neglected. Please note that this is my view and it is not
from any book, journal or publication.

Answer / srinath

even though there is presence of inductance(L=FLUX LIKAGES PER
AMPERE),there is no indicative reactance b/c we are on
operating on d.c.That's we neglect it

I have a 1000 kVA Transformer(11kV/0.415kV) and a APFC panel of 400 kVAR(LT).Now if i want to remove the LT APFC panel and install a HT(11kV) APFC panel on the HT side is the HT APFC panel will work same as the LT APFC panel(improve the power factor),if yes what will be rating of the HT APFC panel?what is the formula to calculate HT APFC panel rating???
