Important Message For the UK electricuity users.... This isn't spam

The UK power companies are now installing digital electricity meters in all homes .
These meters read in KVA hours and not kilo watt hours like the old analogue ones used to do .
Means you guys out there with machines with electric motors and ... transformers, inductive devices ,strip lights will now be charged up to 5 times more for using your power....the new digital meters now read that way.
I'm not happy
I phoned up Ampy the maker of this meter.
And they say it DOES NOT TAKE INTO ACCOUNT POWER FACTOR it reads only in kva hours.
MODEL NUMBER
5235A
British gas my energy provider, say they will not change the meter.
BRITISH GAS SAY THAT EVERYONE WILL HAVE ONE OF THESE METERS INSTALLED WITHIN THE NEXT FEW YEARS
They also say that "ALL" other electricity providers are going down the same route
So therefor you're all going to be in the same boat as me .
IE your overall electricity bills will shoot up 75 percent if you use your machinery in your workshop for a couple of hours a day...domestic
Example I used to use about three units on the old ANALOGUE meter for ...for a couple of hours work in the workshop
This new fangled digital meter now reads 11 units of the same time period .. the new meter isn't faulty ...this guys is the future
I URGE EVERYONE HERE ...WHO HAS ONE OF THESE DIGITAL METERS FITTED TO GET IN TOUCH WITH
ENERGY WATCH

PHONE

They wont have a clue what you are talking about ...but the more people phone this number ...the more this fraud will sink in with them.

Then again to some, but only some, extent it is fairer as non-resistive loads do in fact cause power to be wasted in transmission even if not used onsite. And some kit makes nasty harmonics which make other customers' transformers/motors less efficient.
However if you were to attach a capacitor and your neighbour on the same phase an inductor of the same reactance then you would both be charged under the new scheme though the nett effect on the grid would be (ideally) zero.
In the other case your area just has let's say computers with kind of capacitive-ish loading* and no power factor correction. Now you're paying for the damage to the otherwise clean sine wave.
Or you have inductive loads and are causing more loss in the lines than you are paying for. Now things are fairer under the new scheme.
This is (partly) why new legislation requires power factor correction though one could spend a career arguing about the requirements for a particular applicance.

* Switch mode power supplies start with a full wave rectifier and large capacitor which just might have some power factor stuff in the way.

I don't believe that for a moment.

Don't be silly - even if the meter did read kVAh, there very few loads with power factors as low as 0.2.

I can only imagine that you spoke to someone that didn't understand the question.
Metering is regulated by Ofgem and all meters used for billing have to be certified to a standard (EN 61036). Domestic meters are Class 2 basic accuracy (i.e. 2%). The accuracy might deteriorate slightly at low power factor, but not anywhere near to the extent where it's measuring kVAh rather than kWh.

shows one like mine.
The tech data does say it can optionally register KVAh on reactive models so there could be some truth here.

Where does it say that? The downloadable user manual says that the 2-rate version can be configured to read kVARh (to class 3) as well as kWh (to class 1). This will be for business tariffs where an additional (penalty) charge is made for reactive consumption (kVARh). There's no question of domestic consumers being billed in kVAh.

this is the conversation i had on the phone the other day with ampy's tech department
"does model 5235a correct for power factor" answer ..".No... it does not "
"why are the details of this model not on your web site" .. answer ...it's too new ...we haven't had chance to list it there yet.
I then explained my situation to the techy ..
he said " looks like out meter is wrong for you, in your situation."
"we don't have a domestic meter for your situation .."
I SAID ...
"what am I to do then ...get them to install the old analogue back in ...
he said something along the lines of ... "yes ...I cant think of any other way" ..
OK I said ...will get in touch with British gas and ask them to swap the meter back ...
British gas refused to swap the meter back ...
and this is why I'm quite upset.

Hmm, that could be interpreted in more that one way. I'm still incredulous, but as you clearly think there's a problem I suggest you talk to Ofgem.

These are the facts Andy
Before, over 2 hour period ...I was using 2-3 units over a 1.5 hour to 2 hour session with my machines .
now am using 11 units over the same period
my bills are now 300 a quarter rather than 170 of previous.

Who said anything about mass emailing
The site i listed is the watchdog site for energy .
You guys are hard to convince when some literate character comes up with figures here to disprove what i have said.
get reading your analogue units now ....and take notes of what amount you are consuming in your workshops
and when you get them changed in the future for these digital units and you end up with sky high bills don't come here complaining , when its too late ...

Mark,
If as you say your bill is rocketing, can I suggest you invest in a power meter, assuming of course your kit runs through a 13A plug so that your problem can be quantified. After all just maybe your old meter was broken and under-registering for years. Or just maybe the new one id broken. Does it clock up at the right rate if you put a big resistive load like your kettle or immersion on ?
I bought my meter from Maplin for 12.50 but that was a slightly special price. I think they're normally more like 25. It does VA, A, W, PF, Hz and accumulated kWh.

No my phase converter for my tools is hard wired with 25 amp fuse .
had the mapplin gadget a few years back ...it packed up ... after a week
sent it back ...they said they didn't receive it ...lost my money.
got compensated by the post office for 15 i think though at the time.
after lots of discussion today in the news groups and on forums on the web ... I'm coming to the conclusion ...that either
my old meter was reading low
or the new meter is reading high and faulty.
and it says on it kilowatt hours
so that info i got from the ampy tech guy was wrong.
will phone British gas tomorrow and ask for a test to be run on it .

Future...? "Digital" meters ("electronic" might be a better term) have been common for years, round here at least. My Ampy 2-rate meter was fitted in 1998 - it's so old it's got "Property of Eastern Electricity" printed on it.

I recall no significant change in bills when it was fitted. Mind you most of my workshop consumption is for the storage heaters, with a PF very close to unity. The PF for the house must be lower - lots of CFLs and computer equipment.

One of the difficulties we have is the "five times" claim. Even if the meter was reading apparent power consumption, I can't imagine any set of tools that would exhibit a power factor of 0.2 (which is what we are talking about for a 5x over reading)

A really large unloaded transformer (such as a 3.5kW 110V construction site transformer) which has been left connected to the mains could be the source of large reactive load of extremely low PF.

Well if this is the case? I would strongly object to having this meter installed and insist on the conventional meter put back in otherwise hit them with a phone call/Letter to say you're going to switch to another suppliers tarrif.

Why on earth do you think the lack of a listing of a new model on a web site gives you grounds to object?

Hi Mark
Thanks for the posting
I have just checked my recently fitted meter, we also use British Gas.
My Meter is an Ampey 5224E which says on the front in big writing Multi Rated Watt Hour meter and has a figure of 1000 imp/kwh
It would appear that they may have fitted the wrong meter to your installation
