Electromagnetic Aircraft Launch System - EMALS
The average power required by EMALS is only 6.35 MVA.
The diesels and GTs in QE or POW generate a total of 112MW.
The propulsion motors use a max of 80.16MW.
{VA, volt amps, (or VA or kVA or MVA) is a measure of the complex power in a system, which includes the real power (watts, or kW or MW) and the reactive power. Real power and VA are related by the power factor.
Volt amps = power factor x real power
IF your power factor is 0.9, then
VA = 0.9 x 1000 kW
VA = 900 kVA
Circuits containing purely resistive heating elements (filament lamps, strip heaters, cooking stoves, etc.) have a power factor of 1.0. Circuits containing inductive or capacitive elements (lamp ballasts, motors, etc.) often have a power factor below 1.0. }
So no matter what the PF is, there will be far more than enough power to run both cats at the same time without dropping speed any.
