1A consistent three-phase demand model
A fictional engineering exercise models a balanced sinusoidal three-phase load supplied at four hundred volts line-to-line. Its active input is thirty kilowatts and its power factor is zero point eight lagging.
193 words, under 1 min2Different bases in a short-circuit calculation
A fictional network calculation uses a transformer rated one megavolt-ampere with a six-percent leakage impedance on its own rating. The study adopts a two-megavolt-ampere power base while keeping the voltage base unchanged at the transformer terminals.
