Apparent Power

Some articles on apparent power, power:

AC Power - Real, Reactive, and Apparent Powers
... In this case, only real power is transferred ... Practical loads have resistance, inductance, and capacitance, so both real and reactive power will flow to real loads ... Power engineers measure apparent power as the magnitude of the vector sum of real and reactive power ...
Paul Boucherot - Real and Apparent Power
... The apparent power delivered by a generator as calculated by a simplistic multiplication of the voltage and the current is, in general, greater than the actual (real) power delivered as measured by the work done or ... What is more the total apparent power consumed by two different circuits is not, in general, equal to their arithmetic sum ... Boucherot developed a theorem relating real and apparent power with the introduction of a new concept, reactive power ...
AC Power - Unbalanced Polyphase Systems
... While real power and reactive power are well defined in any system, the definition of apparent power for unbalanced polyphase systems is considered to be one of the ... Originally, apparent power arose merely as a figure of merit ... However, with the development of three phase power distribution, it became clear that the definition of apparent power and the power factor could not be ...
AC Power - Power Factor
... The ratio between real power and apparent power in a circuit is called the power factor ... It's a practical measure of the efficiency of a power distribution system ... For two systems transmitting the same amount of real power, the system with the lower power factor will have higher circulating currents due to energy that ...

Famous quotes containing the words power and/or apparent:

    The personal touch between the people and the man to whom they temporarily delegated power of course conduces to a better understanding between them. Moreover, I ought not to omit to mention as a useful result of my journeying that I am to visit a great many expositions and fairs, and that the curiosity to see the President will certainly increase the box receipts and tend to rescue many commendable enterprises from financial disaster.
    William Howard Taft (1857–1930)

    The apparent rulers of the English nation are like the imposing personages of a splendid procession: it is by them the mob are influenced; it is they whom the spectators cheer. The real rulers are secreted in second-rate carriages; no one cares for them or asks after them, but they are obeyed implicitly and unconsciously by reason of the splendour of those who eclipsed and preceded them.
    Walter Bagehot (1826–1877)
