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.
