Does anyone know the voltage of the power lines running through Chitty Chatty?
 

There are 2 sets of lines, one with triple lines running through the center of the village on tall masts, and another with multiple sets of lines running parallel to Morse Blvd on very large multi-footed towers.

Does anyone know the voltages carried by these lines?

and for the wise ones who will ask "why," I answer "just curious."

220 or 221

It looks like there are both 500KV lines and 235KV lines

"Whatever it takes... ":a20:

and believe it or not, its DC current, not AC. .

and its about 10KV per porcelain suspension insulators. . .

coachk's father worked on the substations in the power industry. .
so she whipped that statistic out.

Nope, Edison lost, Tesla proved that AC was the better power delivery method - less line losses, greater transmission distances, and transformer action allows easy adjustment of voltage - higher or lower as needed. Very very few transmission lines in the USA or anywhere else in the world are DC.

The lines going through Chitty Chatty are most likely 34.5KV, this line is the major feeder to all of the south end of Sumter County.

Excuse me????????? No.

Power is transmitted at high voltage AC because little current is needed. That minimizes that line loss over the long transmission distances.

The responses are shocking.

I call BS!!! No way is it DC...

Hey Don, when they replaced the poles, did they up the lines and voltage ?

Maybe Sportsguy misunderstood Coach K or didn't hear her correctly. Husbands are like that.

I am not sure how wide the corridor is but this is from the Duke website.

44,000- to 115,000-volt lines typically require a 68- to 100-foot corridor

230,000-volt lines typically require a 125- to 150-foot corridor

500,000- to 525,000-volt lines typically require a 180- to 200-foot corridor

If you really wanted to know - rather than get educated guesses from TOTV, you could probably call Duke. Florida: 800.700.8744

"Why" are you curious?

:wave:

Maybe sportsguy also works at a multi state regional utility company with both DC transmission segments and AC distribution segments, and have asked the engineers, and who also has a college friend who is a nuclear power engineer who supervises nuclear power plant construction, after having been interviewed and accepted by Admiral Rickover into the nuclear submarine program at graduation. . .

but don't let that stop anyone from calling BS

it will lite up your life just grab two

Somebody take a multi-meter, climb the tower and check. I would do it, but I'm afraid of heights.

It's entirely possible that it's DC, but only the applicable power company would know for sure.

High-voltage direct current - Wikipedia

"A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems."

Wikipedia has a list of HVDC projects. None of these appear to be in our area. No idea if this list is complete but I would think someone would have corrected it if it was not.

We’ll, all of that Power overhead is effecting the brains and health of the Village People! I see a Law suit coming because the houses are to close to the power lines🥴

Another great question is why Villagers buy new homes located anywhere near these power lines.

And buy near the turnpike

It is not DC. DC is very hard to transmit over long distances.

Gotta be grounded. That's why birds can sit on power lines with no problem.

DC is _BETTER_ for very long distance transmission. It's just harder and more expensive to deal with but once in place, there are no induction losses, no radiation losses and no skin effect. Cable for cable, you can move more power in a DC wire of the same size than the same conductor in AC.

Undersea cables? DC.

The problem with DC is related to converting it to AC, changing the voltages and circuit breakers. It's all possible, it's just a lot more effort to manage.

DC circuit breakers are very interesting as compared to AC. You need to channel an intense amount of energy into resistors while you are breaking the circuit. AC on the other hand, you can just wait for the current reversal and use the air gap. I'm overly simplifying here, but that's the gist of it.

Used to be cheaper houses in "steerage". As all successful marketing strategies improve value, they are a plus for walking dogs in wide open meadows where bald eagles hang out and you can enjoy the hum, pop n sizzle of all that power cruising through the lines - knowing the power is working. Due diligence
research indicated that living near them may cause insomnia and headaches if within 1/10th of a mile; however, so far so good on medical anomalies. Enjoying the savings from yester-years.

More great marketing, close your eyes... it sounds like the ocean with an occassional pop of what sounds like a gun shooting a bird.

Or with kissing Lanai's, to each their own...

AC was around before Tesla was born.

It must be so very frustrating for some folks, making their comments about the southern area, and then to see the continued growth and home sales. Try as they might to convince people that the area is no good but failing to the truth.

HaHa!

There are toooo many smart people on here!! ( yes long O)

As one of my engineering friends in the engineering design company of my utility company described them:

"Its DC with big azz inverters"

Being ignorant, and thinking everything is AC, and working alongside the professionals, I asked a professional. . . ymmv

And driving by the massive substation in Ayer, MA where the canadian hydro power generation created transmission line ends, the substation is huge, probably 10-20 acres where the current into multiple delivery segments. . . to different companies to their central distribution points. I tried to email/call my friends in the generation and transmission companies on Friday but with 50 degrees on Friday in NE, everyone was out of office. . I was hoping to find the exact locations of the inverters. .

What i find really interesting is that the amount of energy is measured for usage and billing.. . and monitored at many points along the way. in 1/4 of MA and 1/10th of NY geography, we have over 50,000 mobile cellular devices monitoring the transmission and distribution system, and growing every year. ..

Read the book "Shorting the GRID", by Meridith Angwin. . . .

ooops, going down the financial analysis path and with 4 months of work left, . . I have got to let it go. . .

I......am.......IRONMAN !

From some of these technical answers, it seems we have Scotty from Star Trek living among us. Awesome!!

My electric golf cart runs 5mph faster through that section. Just saying :1rotfl:

Looks like 500KV

Transformers
 

Why does the system requires Transformers then???

Transmission lines
 

As a retired energy guy I can affirm that those transmission lines are AC. While a whole lesson in electric transmission is impossible on this forum, I’ll give you some info that should satisfy some of your curiosity. The whole Eastern Interconnect is AC with a little DC going to some isolated large use customers. We are part of the Eastern Interconnect. The US Eastern Interconnect goes from Canadian border to southern tip of Florida to the Rocky Mountains, but not into Texas. Texas has its own DC Transmission Interconnect. ERCOT. West of the Rockies is the Western Interconnect. The Canadian electric system has some DC that has special rectifiers where their system meets the Eastern Interconnect. The high voltage of the transmission lines throughout the Eastern Interconnect is all AC and the voltages vary from 138,000 volts (138 kv , 230 kv, 250kv, 345kv, 500 kv, and also some 765kv) 500kv has multiple strands for each phase, and 765 kv are monsters that you won’t see around here. You can distinguish higher voltages by observing the distance that lines are separated. The three lines that you see running parallel to each other are really one transmission line as each line has 3 phases. So if a tower has three lines hanging on it that tower is supporting one transmission line. If you see 6 lines then the tower is supporting two transmission lines. Check the size/ length of the insulator holding the lines and the longer set of insulators with tell you which line has the higher voltage. Ignore the small wire going across the top of the transmission tower as those are for lightning strikes. The voltage you’re asking about is probably 230kv, and 345kv.
