what is the effect of power factor to (a) voltage (b)
transformers (c) generators (d)transmission lines
Answer Posted / md gufran yaqub
a)decrease in pf results higher Voltage drop
b)with low pf reactive current of transformer results in
losses due to magnetic effect, eddy current with poor
regulation.
d)higher the pf low transmission losses,higher
efficiency,low VD, reduction in conductor size hence
economic to tranmit power at higher voltage and power
factor.
