high frequency conductor rating/losses
high frequency conductor rating/losses
(OP)
I'm seeking recommended published material concerning selection and use of standard building wire in the distribution of high frequency (~800 Hz) source voltage. The academic papers I've stumbled across so far have been thin on practical application guidance. Any forum help or insight is appreciated. _80127

Also, the skin effect will make the resistance higher.
A standard Electrical Engineer's Handbook should provide you enough data on the wire characterisitics to work out an equivalent circuit at 800 Hz.
Unless you meant 800 kHz?

I'm familiar w/the use of non ferrous raceway and when I apply the Table III CDF (Current Derating Factor) of .77 to a 4/0 cable I'm left with that conductor being good for 177A (NEC Table 310.16, 75C). Two #3s would provide equivalent ampacity.
Much of the material I'm coming across is heavy with error cancellation techniques. I'm not rejecting the need for detailed understanding of the phenomenon... I'm hoping to find a valid approximation in 'industry practice' type literature. _80128

I would frankly be more concerned about any type of overcurrent device you might be using. You can probably find molded case circuit breakers and fuses tested and rated at 400 Hz, but I'm not sure anything has been tested much at higher (fundamental) frequencies.
If this is something that would actually be installed in a building, you would have to deal with all of the necessary agency approvals required for all of the electrical components.
