Thus for a particular Power Factor, we can get zero Voltage Regulation. As VR = 0 tanƟ2  = -R02 /XO2 Therefore Magnitude of Power Factor CosƟ2 = xe2 / ze2 Here negative sign in the value of tanƟ2 means that power factor of load is leading. Thus zero Voltage Regulation is achieved by leading load of power factor X02/ Z02 and if we increase the power factor of load beyond this value then Voltage Regulation will become negative. Negative Voltage Regulation means that Secondary Terminal Voltage V2 is more than the no load generated EMF E2.
