working of Power lines

You see power lines everyday but do you know why they look like they do or how they are designed. Lets dive into the everyday so we can become a little more well rounded. Lets also dive into a little theory over it.

The working of a power line are quite simple. the number of lines correlate to the number of phases as each line is a different phase. In short

4 wires: 3 phase system with a ground wire

3 wires: 3 phase system

2 wires: single phase (usually at distribution)

1 wire: high voltage line or rarely a earth return

These are all simple cons pets be side the earth return that you can easily find information on. But the earth return is a little different. simply put it uses the ground as the ground for the circuit.

When looking into power systems there are a couple more things to keep in mind with as well. Two of the more common things are inductance and capacitance.

Long story short there is inductance going between the power line or more commonly but transmission lines. This is because of the magnetic force created between the lines and capacitance created between the lines and the earth. if you care about the math here you go.

for inductance and

For capacitance. Over all Transmission lines are quite simple. There is more this this as anything else but our goal is for a simple explanation. If you have any questions feel free do DM us on Instagram @weacreation. Stay creative @wac
