Reactive-Factor MetersAuthor: E.E. Kimberly The reactive power changes more with a given change of load phase angle near zero than does the active power, and hence a reactive-factor meter is more accurate than some types of power-factor meters near unity power factor of load. Reactive-factor meters are preferable for use with synchronous converters (see Chapter 29) because of the delicate adjustment of phase angle desirable in the operation of these machines.
