why 400Hz is used for aircraft systems ?
Answer Posted / rajavel.k
Aircraft electrical components operate on many
different voltages, but most aircraft systems use
115 volts AC at 400 Hz or 28 volts DC. 400 Hz
offers several advantages over 50/60 Hz, namely
by allowing smaller, lighter power supplies to be
used for military hardware, commercial aircraft
operations and computer applications. Reducing
the space and weight requirements of electronic
equipment improve aircraft thrust and fuel burn.
Along with the higher frequency and advantages of
the 400 Hz system comes more sensitivity to voltage
drop problems—both resistive and reactive. Thus,
in order to properly test and monitor the
performance of aviation power systems.
