Mains power voltage drop to reduce usage?

[Commander Kinsey]

Pah! Too many amps and not enough volts. What a pansy supply, and an utter waste of copper.

[Carlos E.R.]

Sure. And be fined. And get another smart meter, or no electricity at all.

[Carlos E.R.]

I just do :-)

LOL. You really do not need more.

What do you need that much electricity for, you run a forge at home? :-D

[Carlos E.R.]

Because they are friends with the electricity companies, and they asked nicely. Meaning, they both got more money.

Well, no such thing here. This is a modern country :-D

In the UK I can have up to three phases, which would give me 75kW.

According to this page it's 4 grand assuming you have three phases within 20m, which I do, under the pavement outside my house, since all three phases run along there to supply alternate houses with one phase each.

But that page says something very stupid: "Most houses in the UK have a single-phase power supply, which is sufficient to power a 7.4kW EV charger but nothing more. If you want an 11kW charger for an EV, you must upgrade to a 3-phase power supply, which requires modifications to your electrical installation." UTTER BULLSHIT. Why on earth can't I run an 11kW charger off a 100A 240V supply giving me 24kW? The answer - you can if you don't bother with regulations, fit it yourself!

[Commander Kinsey]

Which would surely negate the point of dropping the voltage in the subtransmission?

[Commander Kinsey]

It's only illegal if you're caught. You could blow up your neighbour's meter.

[Commander Kinsey]

An electric shower is 9kW. An electric cooker is 8kW. Does everyone in your country have cold food and cold showers or use gas?

In my case, a supercomputer.

[Commander Kinsey]

Didn't you recently have a terrible poverty? About a decade ago?

[Jim Joyce]

That works, thanks.

The facts are the facts.

3 % voltage reduction results in 1.5 % demand drop. 5 % voltage reduction results in 2.6 % demand drop. Been there, done it, seen it. < no T-shirt though >

If the final substation compensates for the voltage change, obviously you would achieve nothing, just stop and think....

[hubops]

Don't need to stop & think - it works - - afaik it's used by most utilities in North America. It's tested once or twice a year. John T.

[Commander Kinsey]

It only works because some substations don't compensate. Once they upgrade them all, they've shot themselves in the foot.

[Commander Kinsey]

Why do you need twice as much as UK residents?

[Phil Hobbs]

Not to mention hydro!

It's been used for about 50 - 60 years - that foot has healed-up long long ago ! It's not just distribution stations that are supplied from the sub-transmission feeders - commercial, industrial, residential, etc .. much with fixed tap transformers. John T.

[Commander Kinsey]

Air conditioning consumes a lot less than heating.

Ah, that's your name, I wondered why kilowatts was being written at the end of everything.

[Commander Kinsey]

Why are they still fixed tap?

[Carlos E.R.]

Hardly. My meter is inside my house. Even if you don't get caught, they would replace with another smart meter. You gain nothing.
