That has to be dealt with even when everything is overhead.
Yes, but with overhead adding conductors or another circuit the cost is nothing compared to UG
True, but a spare raceway where you know someday you might need it saves excavation expenses or even demolition/and replacement of pavement, landscaping, etc. Like I said this maybe not so easy to know were to do so with general MV distribution as it is for service runs to individual customers though.
For UG, the only way to add capacity is re-trench, add additional raceways in a duct bank for future installation, or over-size raceways to pull larger conductors in the future. I'm guessing re-trenching is the most expensive option, but I have no idea what the additional challenges might be for other options. Looking to learn things.
I could see a spare or oversized raceway in strategic locations in primarily residential/light commercial neighborhoods would allow to increase capacity to select spots where you can then divide it up accordingly. But should some larger industrial loading come along you very well bringing new or updated ability somewhere near the location regardless.
local distribution is typically in the MV ranges. Don't know what the industry calls the ceiling for this but about 15k or less is pretty common.
What do they call over 230 kV? We have a transmission line at 345 kV here in Michigan.
Ludricous voltage?
Extra high. There’s also an ultra high over 800kV. (China)
We have a couple of major ones running thru here of 750kv just to send power to NYC, and a 500kv. Not sure of the process that is happening but you can walk under it on humid days and hear it buzzing. I've seen Maintenance crews here riding a gondola along the wires inspecting the cables, definitely not something I'd want to do. I assume though if you were to ground out on that much you'd never know it, you're gone almost instantly. Also seen these insane guys:
His brother is probably one of those freaks who climbs 500 foot radio towers to change the bulb for the warning light.
I was thinking about "ludricous speed" from movie Spaceballs when I said that BTW.Ludricous voltage?
What are these guys doing other than maybe getting a close look at what condition the conductor may be in?
"They've gone to plaid!!"
How about better maintenance of what is there, as well as better maintaining of combustible debris on the right of ways for those lines so that when sparks do fall from equipment there is lesser chance of starting a fire?
