What is the power factor you maintain at ur organization?

Answer Posted / selvan

Power factor is ratio of real power to apparant power.In
industries maitain the powerfactor is important one.But not
maintain the powerfactor in unity, Loads varied form time
to time.In industries induction motors and tubelights
mostly used. This are inductive loads,this loads create
lagging powerfactor.So to improve the powerfactor by using
static capacitors,syncronous condensor and phase advanser.
