POWER FACTOR P024
In direct current applications, watts are defined as voltage times amperage, but in alternating current the voltage leads or lags behind the amperage.
Power factor is a measurement of this leading or lagging. The power factor at which a motor operates is dependent on the design of the motor, and is established at rated voltage, frequency and power output.
Power Factor = Real Power/Apparent Power
Power factor can be improved either by purtchasing motors with inherently high power factor (synchronous motors,) or installing power factor correction capacitors.
