I have installed capacitor bank at secondary transformer.
cos phi is increase. but on load (far from transormer), it
still poor. Can anybody explain it??
Answer Posted / vikramsena_reddy
first a fall caluclate the reactive power. after that
according to reactive power caluclate requied capacitor to
be arrange then u will increase power factor.
kVAr = KW {tan(cos^-1 Phi e) - tan(Cos^-1 Phi d)}
Where - Phi e = existing Power Factor.
Phi d = Desired Power Factor.

I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
