Are power lines electrical energy

Answer 1

The power lines carry alternating electrical current and voltage. This produces an electrical and magnetic field around the wire. Some of the electrical energy thus escapes in the form of electromagnetic radiation. The wires do not carry the radiation. They radiate it because of the electrical power flowing in them.

Answer 2

Canada and US To best explain this, visualize the three primary line that you see on pole tops in industrial areas. The voltage between these three lines is about 14,400 volts. When you see a pod of three Transformers mounted together they are combined into a three phase system. From each of the three high voltage lines the voltage goes through three separate fuses and down to a high voltage bushing in each of the transformers. Inside the transformer the voltage goes through a coil and exits the transformer through a second high voltage bushing. This bushing is tied into the ground pad completing the circuit. This connection puts 7200 volts across the transformers primary coil. The secondary voltages of these transformers are determined by the customer that wants the three phase service. It could be 600,480 or 240 volts. Each single transformer has two output bushings. These bushings can be wired into either a delta or star configuration depending on what the customer ordered. In a single phase service the name is derived from just using one of the three primary lines that are used above. It is the same primary connection, but the secondary is a bit different. The output secondary coil has three bushings coming out of the transformer. On the two outside bushings is the working voltage (house connections 240 volts). The middle bushing is a center tap of the secondary coil. This gives a voltage of (bushing left to center 120 volts) and (bushing center to bushing right 120 volts) These are the the three wires that come into a house for its 120/240 volt service.

Answer 3

No, but they do carry electrical energy.
