Power (Energy) Transmission

06/09/2011 6:20 AM

60hz power from hv tr-er 20/230kV delivered to 100miles away load s/st. over wires of overhead line or dielectric substance(air between wires, for example). May anyone clear it up. Thanks in advance

60hz power from hv high Voltage tr-er transformer 20KV/230kV delivered to 100miles away load s/st sub-station. over wires of overhead line or dielectric substance (air between wires, for example)

What is the clarification you need?

Air between wires is of course the expected dielectric for 230KV line.

I am just curious and most of the people who are professional el. engineers just responded with joke or said ya... definitely 60Hz power propagating through the wires and air or dielectric around is necessary only for arc prevention.

Do you want someone to calculate the losses for you?

Do you want someone to calculate the conductor sag for you?

What, exactly, do you want?

Is this homework, or your real job, or are you just curious?

I believe OP wants to know if 60Hz power is transferred via the copper or through some other medium like a radio wave through a dielectric as per Tesla...

To answer the question...60Hz power is transferred through the copper, Radio Frequency power is transferred on the surface of a conductor and/or through a dielectric medium such as air or a vacuum.

Dear guys.

After exploring some books I did learn that 60/50Hz power propagating through dielectric substance between the wires( central conductor and shield in case of cable)but wires are necessary to provide electrical field and this is true also for DC current transmission.Very interesting.
