Something not mentioned is this which is a factor. Although as far as I am aware we knew about it in underground cable chambers in the 80s. Traffic vibration causing stretching in cables, particularly on long straight fast roads more than in housing estates.

This is west LA. There are no fast roads! ;-)

Great read. Everyone thinks of infrastructure as the stuff behind the scenes that is simply "there", and just works, and not worthy of any attention or respect. The reality, as you and I know, is that getting it to that point takes a ton of hard work.

Many years ago, I interned with the team at Eskom (the South African power utility) that did “live lines” work on the transmission grid. Typically 400kV, but some up to 1.5MV, both AC and DC. It’s amazing work - very safe if you follow the rules - but instantly fatal if not.

One fun thing was a long (10m or so) fiberglass pole for poking switch gear. The pole came with a cloth: you had to make sure it was super clean and super dry before poking anything with it.

One time an underground HV cable failed and downtown Auckland had no power for 6 months while they fixed it.
