How do I calculate voltage drop in a 400Hz system?

How do I calculate voltage drop in a 400Hz system?

How do I calculate voltage drop in a 400Hz system?

(OP)
I am looking for helpful information on performing voltage drop calculation on a 400Hz system.
Any pointers will be greatly appreciated.

RE: How do I calculate voltage drop in a 400Hz system?

There should be no difference as long as you use appropriate R and X for the higher frequency.  R will be higher because of skin effect.  X will be higher because it is proportional to the frequency (X = 2·pi·f·L).  There is also a skin effect for X as well as the proportionality.

Alternatively you can utilize software for power flow like ETAP. Change the project frequency to 400 Hz and when you select 50/60Hz cables from the library, ETAP automatically calculates the new impedance based on 400 Hz. I have seen this application used for shipboard power systems.

Toro, Is this for a 400Hz aircraft power distribution system? If so I've got loads of info. If not, I'll wait for more posts so as not to waste time.

hgldr...please share the information irrespective if you dont mind. I am interested in looking at it. thanks. :)

Yes the calculation is for aircraft ground power units (converter).
Thanks.
