In triangular configuration inductance is of low value then
that of straight line configuration. Low value of inductance
increases power transfer capability and posseses several
other advantage hence it is preferred.

Answer / jithendra

phase to phase clearance

In High voltage 11KV min 400mm 33kv 600mm distance should be maintain, so they are formed in triangular (it is called as triangle formation)

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
