Mains power voltage drop to reduce usage?...

[Peeler]

On Sun, 06 Nov 2022 17:13:37 -0500, hubops@ccanoemail.com, another brain
dead, troll-feeding, senile CRETIN, blathered again:

Primary load is automatically shed - to maintain very stringent
system frequency limits. The big thermal generators are very fussy
about system frequency.

\" Small frequency deviations (e.g., 0.5 Hz on a 50 Hz or 60 Hz
network) will result in automatic load shedding or other
control actions to restore system frequency. \"

Well given its not invested in energy infra-structure so supply is often
\"flaky\" makes it feel a bit like that at times.

Given your idiotic replies to the trolling wanker\'s trolls makes it feel
that you might be a typical troll-feeding senile asshole.

They run it on the higher side of the range
to reduce line losses.

some power quality limits here - just as an example :

You\'d better worry about his and your limited mental capacities,

The electricity companies know this, and will not do a brownout, but

If by brownout you mean a system voltage reduction < ?
In North America, typical voltage reduction is:
A 3% voltage reduction will lead to about a 1.5% reduction in total
energy consumption (for a load of 20,000 MW this represents about 300
MW)
A 5% voltage reduction will lead to about a 2.6% reduction (for a load
of 20,000 MW, this represents about 520 MW
.. see if this link below works < ? > :
The paragraphs on Voltage Reductions are about half-way through.

https://www.ieso.ca/-/media/Files/IESO/Document-Library/training/ORGuide.ashx

I\'m not a power expert, but I suspect this is about power distribution
between the generators, very large scale. Not the voltage given to
customers.

The vast majority of customers will never notice.
Your normal household supply of 124 drops to 118 - maybe -
... if the distribution transformer doesn\'t have a tap-changer
to compensate for the grid / sub-transmission 5 % reduction.

Not necessarily. We have a \"guaranteed\" minimum and maximum supply

Yes, all sorts of issues if a power company messes around with the
voltage and frequency. If a consumer wants to attempt  saving money in
this way then the obvious thing to try would be a variac. It won\'t
change the frequency but does enable one to reduce the supply voltage
easily to whatever device you wish to reduce the power to.

Not the same thing at all.  If you want to reduce usage, you turn things
down or off.  If the whole country wants to do that over a short period
due to high demand, they can\'t very well phone everyone up and tell you
to delay your coffee for half an hour, they have to lower the voltage.

As has been explained, reducing voltage is a crap idea. You can email
folk
and ask them to reduce consumption at peak time though. I got refunds
last
December for doing this.

Not so accurate though.  Could they get you to turn things off at a few
seconds notice?

Eventually when we’re all on smart meters, more variable tariffs will
become available that will encourage this behaviour will become the norm.

No smart meter will ever be installed in this house.

There is a type of electricity contract in which you accept the

Well given its not invested in energy infra-structure so supply is

I\'ve heard some parts of Italy only have a 3kW supply to each house!
They have problems when buying 3kW kettles!

I have 2.3 KW on my entire house.

Typically, most homes have 3.6 KW. Max you can have is 15 KW.

Do you really want a meter which can overread by a factor of 5,
in particular on eco-stuff like LED lights!

Its worse than that, you pay for it on your bill. Mine costs
0.026667€ per day. I also have a contracted peak load. Exceed this
and it cuts out. That costs 0.091474 Eur/kW/day and changing the
value costs a fair amount.

What is your peak load? Is this certain times of day only? I can
draw 24kW, if that reduced I\'d be fucking angry.

In the US, 100 amps (50 amps on each of the 2 120V legs)
or roughly 12 kw, was the standard for 1950 onward. It\'s been
upgraded to 200 amps, or 25 kw, for a bunch of decades.

John T.

The 3 % / 5 % voltage reductions are applied to the
station busses that supply the feeders -
- sometimes called sub-transmission - 14 / 28 / 44 kV .
Not at the higher transmission voltages.
It\'s not unheard of for a subtransmission distributing station
to have only a fixed-tap ie : no automatic tapchanger
for voltage regulation - so those customers would see the
3 % 5 % reduction - if they were intent on measuring it.
Many distribution stations have on-load automatic tapchangers
which will correct the voltage to the customers ! imagine that.

reason for the old term \'brown out\'. Most modern
devices would not work and might even be damaged.

So No.

A device getting damaged by not enough power is
screaming of bad design.

Not necessarily. We have a \"guaranteed\" minimum and
maximum supply voltage. Why should a company spend
extra designing and installing protection against
supplies (not temporary aberrations) outside them?

Yes, all sorts of issues if a power company messes around
with the voltage and frequency. If a consumer wants to
attempt saving money in this way then the obvious thing
to try would be a variac. It won\'t change the frequency
but does enable one to reduce the supply voltage easily
to whatever device you wish to reduce the power to.

Not the same thing at all. If you want to reduce usage,
you turn things down or off. If the whole country wants to
do that over a short period due to high demand, they can\'t
very well phone everyone up and tell you to delay your
coffee for half an hour, they have to lower the voltage.


As has been explained, reducing voltage is a crap idea. You
can email folk and ask them to reduce consumption at peak
time though. I got refunds last December for doing this.

Eventually when we’re all on smart meters, more variable
tariffs will become available that will encourage this
behaviour will become the norm.

In Spain, where every one has to have a Smart Meter, there are
three different price bands.

I wasn\'t aware Spain was communist.

Well given its not invested in energy infra-structure so supply is
often \"flaky\" makes it feel a bit like that at times.

I\'ve heard some parts of Italy only have a 3kW supply to each house!
They have problems when buying 3kW kettles!

I have 2.3 KW on my entire house.

How the hell do you manage with that little power?

> Typically, most homes have 3.6 KW. Max you can have is 15 KW.

The dark ages.

Do you really want a meter which can overread by a factor of 5,
in particular on eco-stuff like LED lights!

Its worse than that, you pay for it on your bill. Mine costs
0.026667€ per day. I also have a contracted peak load. Exceed this
and it cuts out. That costs 0.091474 Eur/kW/day and changing the
value costs a fair amount.

What is your peak load? Is this certain times of day only? I can
draw 24kW, if that reduced I\'d be fucking angry.

LOL

Of course I don\'t often use that much, I\'ve never gone over 18kW, and not over 8kW for any long period.

In the US, 100 amps (50 amps on each of the 2 120V legs)
or roughly 12 kw, was the standard for 1950 onward. It\'s been
upgraded to 200 amps, or 25 kw, for a bunch of decades.

We can have more, on a home, switching to three-phase system. And way
more expensive.
