[MoiInAust]

There is a BIG difference between RMS Power and Peek Power,


Woof...

My alternating current theory is rusty, but couldn't that be due to
the difference between VA (Volts * Amps) and Watts?

** The power factor ( PF) for most CFLs is around 0.4 to 0.5 - so
a 23 watt rating corresponds with 50 VA.

For comparison, my desk lamp uses a 15 watt fluoro tube with an iron
core ballast choke and starter in the base - it has a current draw
of 310mA.

Makes the PF = 0.2


...... Phil

So the next question is
'What do we actually pay for on our electricity bill?'

Graeme


Well, it's supposed to be based on so much per kilowatt-hour, not kVA,
so I hope we are paying for watts, not VA.

Hope to be paying less soon. A 1KW solar cell jobby going on roof. Cost
to me $355 cost to the feds $8000. Only problems night & clouds.

Crikey, that's practically free!
Where do you live?

Dave.
The Qld government had a lottery and I was toooo late for it, but they
arranged a contract with a company to supply at $355 above the feds
rebate, which I got approval for the other week. Oh the feds are dropping
the rebate to $7500 soon.

Damn, you got lucky.
Last I looked it was like $14K to install a 1KW system in Sydney, so approx
$7K out of your own pocket.
If it dropped to say a few $K difference it'll be a no-brainer for me.

Dave.

They are advertising a $4K difference with local Toowoomba company here. Get

onto you local polly and start a movement to get a similar scheme started.
Costs the states zip, as the feds pay & the contracting company is as busy
as hell on a hot day.

Surely with a purely resistive load VA is exactly the same as Watts?

Sure is, pity a CFL is nowhere near a "purely resistive load" though.

"Peek power"? Is that when you glance at the power meter?

He's a pervert who tries to peek up Miss Power's short skirt to see
if she is wearing panties! Did you notice the mirrors glued to the top
of his shoes? ;-)

Err. They *do* shatter.



My Woolies 23W job draws 210ma therefore it is a 50.4W globe. Is there a bit
of skullduggery going on here?????????

And what is the phase angle?

** It is undefined.

Cos you are not dealing with an all sine-wave system.

* PF = watts / VA *


Note: no cos phi in sight ......

There is 4 page "advertising report" lift-out in todays Sydney Daily
Telegraph about home solar systems.
One local company SolarSave (www.solarsave.com.au) is advertising a 1KW
system for $1,990 "fully connected".
Will have to look into it all...

$2K, won't take long to recoup at that price. Still get onto the pollies, ya

never know one have a working brain cell. I am working on a average output
of 8KWH a day. So at $3 a day will reduce my power bill and pay for itself
in less than 2 years. The pollies think it is cheaper to put these on a roof
or seven than to build a power station, well it is quicker. What are the
emisssions like at the factories that make these? Still gotta be less than
10 years of coalie.

Would be interesting to hear what you find.. Last time I looked, it was
all massively out of our price range..

typically fairly small, often current is leading by a few degrees.
the main reason for the low power factor (if you must analyse them in
the frequency domain), is all the harmonics.

...

Isn’t this the coolest looking light bulb you’ve ever seen? Philips’ new
Master LED light bulb gives as much light as a conventional 40-watt
bulb, but with a 45,000-hour lifespan, four times as much as a CFL and a
total power consumption of seven watts. However, with a price tag of $50
to $70 per unit, replacing all light sources in your home with LED light
bulbs could become quite the project. The Master LED Light Bulbs are
already on sale in Europe, but we won’t see them here in North America
until next July.
