Answer / biplab

In 3phase induction motor,.....p.f=R2/(R^2+sX^2)^1/2

so directly related to slip.now if p.f reduces,slip increses
thus Nr(Rotor Speed) becomes slower..

Answer / rskh

active power is always depend on p.f.so,It's highly
considerable point.

Answer / simon peter

The ohm's say's V is directly prop to I it means if v raises its value the value of I. will raise automatically. The formula of P.f=v*i*cos fie. Hense if the value of V is increased then the value I will increase .Motor will draw less current , v from the supply & it will b known as good power factor of motor .

In case of delta/delta transformer if the one phase is blown out then what will be secondary line voltage ?
