WHAT IS POWER FACTOR (PF) AND WHY LOW PF IS BAD

摘要

Here only a brief summary of the Power Factor and its significance is given as the more detailed account can be found elsewhere [2].rnWhen the load resistor R is placed directly across the utility line such as shown in Figure 2a, the sinusoidal line current iAC drawn is directly proportional to and in phase with the sinusoidal line voltage vAC as illustrated in Figure 2b so:rniAC(t)=vAC(t)/R(1).
