Had to Google 'imaginary power'... Not a lot of experience with high-power AC
stuff! :-) ('Imaginary power' is probably not the best term to use, because
there are actual currents involved; I like the 'reactive power' name better.)
The article I read said that in reactive load which is high in inductance
(which is, I assume, the source of the high reactive load in rotary
convertors - or am I confused - a common happening, I concede :-), judicious
application of capacitance can reduce the reactive load. Why isn't this used
with rotary convertors to reduce their reactive load?
Any idea what the active and reactive powers/currents were in that attempted
