Reading this I wonder how the circuit is actually closed? Are there always pairs of conductors on each line?

- howard941 7y agoIt depends on the circuit. A single phase transmission system in the SWER configuration gets by with a single current-carrying conductor https://en.wikipedia.org/wiki/Single-wire_earth_return https://en.wikipedia.org/wiki/Single-wire_earth_return
- hoofhearted 7y agoWhen the power is generated, it is usually done so by a 3 phase generator that is separated by 120 degrees of rotation. All 3 phases inside the generator are bonded together on one end. The other end are the 3 current carrying conductors leaving the generator. The bonding of the phases on each side of the conductors is what creates the closed circuit. https://en.wikipedia.org/wiki/Three-phase_electric_power https://en.wikipedia.org/wiki/Three-phase_electric_power
