Answer / harish

the power factor can be presented practically
by drawing the phasor diagram...it is the angle between the
voltage and current....the positive direction is assumed i.e
either cc or acc.....

Answer / satya

power factor is the ratio of p and vi so we can take the
gralph between p and vi and slope of that gives us p.f

Answer / yuvraj

PF= 1/ROOT(1+THD2)

Answer / moti rgpv

TO MEASURE PF PF-METER IS USE.DRAW ANGLE B/W PF AND TIME

How do I know if a transformer is saturated? I am doing the simulation of the saturation of a transformer, but what parameter tells me when a transformer is saturated? How do you calculate? is on the plate?, there is a rule that can help me? How could model? I understand the saturation occurs when the flow can no longer bind to the other winding, this is given to certain current, this current is the same that appears as the highest in the bale of features? Thank you for your help Eduardo Alvarez Guatemala
