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 !

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."

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:

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.

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.

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.

Do you believe that?

what he said

Believe the one with 3 big wires and 2 small wires on the same tower are 500,000 volt wires(3), the other small ones are lightning protect wires. The other towers with 6 big wires are 230,000 volts.

You have no business knowing this unless you are a lic. electrical company
