ER FACTOR 1,107 power factor is unity. Hence, to keep the power factor as nearunity as possible is one of the chief problems in alternating currentdistribution. Ques. Can the power factor be less than unity if thecurrent and pressure be in phase ? Ans. Yes, if the waves of current and voltage be… … Fig. 1,348.—Case of synchronism of current and pressure with power factor less than unity.Suppose the waves of cun-ent and voltage to be in phase, but distorted in form, and notsymmetrical, so that they do not run uniformly together, as shown in the figure. Thenthe real power factor may not be…
