But what if the huge distribution systems used DC and the whole
thing
was only converted to AC close to the users in small installations? This would get rid of the frequency problems.Basic physics. To run DC at the power levels required, the "wire"
would
have to be over 100 feet in diameter IIRC. Look up the Edison vs.
Tesla
power arguments for all kinds of information on AC vs. DC.
Huh ? Where in the physics of ohms law is Hz a factor ? Having lived off the grid, where systems are often at max 48v, yes the wires have to be several 0's of gage to carry the lagre amperages. Much the same in A/B DC legs in a colo. Up the volts and the amps go down to produce the same power (watts or work). I am a little rusty on this one, but I seem to remember that AC travels only on the outside skin of the wire but DC uses all the wire.
