I give up.
All I'm saying is that the watt is an instantaneous value, something you've already agreed.
OK. You know that
And, from your previous post, you know that a watt is an instantaneous value. And you know that if you sustain that for a period of time, you get energy. One watt, one second, one...
Far too risky to make assumptions.
If you want energy, you need a time period.
Then you get joules, ws, kWh.........not watts.
The watt is an instantaneous value.
I made no claim that the speedometer could do so.
No interpretation required.
Well, I would expect a sales pitch to to take that line.:p
But 20% of the kVA rating versus 100% of kVA rating?
No approaching about it.
Speed is an instantaneous value.
The blue car I had, the one in the avatar, could get from 0-60mph is six seconds.
Graph speed against time and it would be an ever...
It's irrelevant and thus superfluous.
A bit like saying "a round circle".
So yes, with respect, you do seem to be struggling with the concept.
I'm with Goldilocks. I don't immediately see how. As he says, you would need the autotx to be at the motor end which would not help reduce the cable current. If that is your problem. Do you know what...
We would use just one three phase unit. Since the voltage increase required is quite small, the kVA rating is also quite small.
I don't know why you would consider using two or even three units.
Some figures I calculated for one of our drive projects - as it happens, figures that we were contractually obliged to provide and meet.
Calculated Performance LRT "2/4" "3/4" FLC...
First of all, welcome to the forum!
Not a lot of information to go on.
A step up autotransformer, as many here would call it, could be used to get the voltage back to where you need it to be. But...
And can save a bit of typing.......
Don't believe I did.
All watt values?
There aren't all watt values.
It's a single derived SI unit.
The watt (symbol: W) is a derived unit of power in the International System of Units (SI),...
Cite any substantiated source that proves that the watt is not an instantaneous unit.
Fair point and ought to be taken into account.
I think it was presented quite lucidly if I may say so.
It is usual for distribution transformers in UK to be delta star with the secondary star point to be earthed (grounded) at the transformer. I...
Fine. Cite any substantiated evidence that proves that the watt is not an instantaneous unit.

It's a simple statement the watt is an instantaneous value.
That is not a matter of opinion.
I had a quick check back through the thread and found these comments:
Rate is an instantaneous...
Or a bad smell.
