They don't have fuses, lol. Computers monitor the load and trip the lines off it it gets above what they are rated for.

Are you sure they don't have fuses as well?

I’m guessing it varies by region but in the places I’ve worked in Canada the power lines are all controlled with circuit breakers which in turn are controlled by older electro-mechanical relays or newer digital relays. Also a lot of lines have fuses protecting them on top of that

Yeah, they are wrong. The pole right by my house has a fuse on it.

Your pole isn't a high voltage transmission line.

This is Texas we're talking about remember. They're light-years behind having advanced technology like fuses.

Some lines do have fuses. There is a power pole about 50 feet from my house and it has a fuse. I have been on the front porch when the fuse blew. It was very loud. Just google power pole fuse and look at the pictures.

Bro, we're talking about the transmission network which means 100kV+, not your little 13kV distribution feeder.
