what you mean by vector group of a 3 ph transformer
Answer Posted / suthar bharat
using vector group of a 3ph tranformer ,we can say that ,it
defined different phase angle between primary winding and
secondary winding. Like ,different group 0',30',-30',180'..

As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.
