Underground laying of high voltage lines brings very very high costs as well as greater dielectric losses, and it costs a lot more to find a fault and dig down and fix it.
That said, many downtown areas went underground decades ago, and also placed the wire in underground tunnels with other services. The underground mesh is a very comple beast in many places.
- aeternum 5y agoThere is cool tech to find faults near exactly. You just send a pulse down the line and wait for the echo then make some calculations based on the speed of light. One of the most amazing things upon arriving in SF was how many ugly and dangerous power lines were strung all over the bay area. I grew up in a much poorer area but we still had underground lines. Everyone knew to call the electric company before digging, it wasn't an issue at all.
