Answer Posted / rahul bhimani
power factor will be unity when Kw(real power)=KVA(reactive power).i.e P.F=1 ,Now if P.F >1 means reducing KVA ,so one point comes only Kw flows through the line.
Another way power = VI(cos@) ,where cos@ is P.F & @ is angle between voltage and current . so Power =VI when @=0 ,Power =0 for @=90 ,power = -VI for @=180. That means if phase angle between V & I is vary so power delivered to the load will be vary.So pure real power flow only if cos0=1.Means V&I in phase.
