Voltage Stabiliser

[sponge23]

Exactly Dave! I can count on one hand the times I've measured 230V at source!

Ok..
firstly, our nominal voltage is 230v (+10% -6%), the same throughout Europe.

Voltage dip.. Does the voltage not also dip in Europe or does that just happen in the UK?

wrong, the nominal voltage for new supplies is 230.

it is too costly to swap all supplies in the country to 230 from 240, a lot of machines etc wouldn't play ball

Nominal voltage yes, actual voltage no.

Nominal voltage is what the politicians agreed to for whatever reason, actual voltage is what the output of the thousands of substation transformers around the country is. I believe the standard DNO transformer still does give 250V output, but there are other people on this forum who can confirm this.

Yes of course voltage dips everywhere, but that doesn't mean that they don't have to use some form of stabiliser for the machine in those countries.

going back a bit for 250 arnt ya? wasnt the last one 240?

i have only come across 252 once

The nominal voltage for every supply is 230/400
The actual voltage is more like 240/415 although the transformer will more likely be outputting in the region of 250/440 for all supplies, new or old.

230 +10% -6% throughout Europe!

the main reason was for import/export. Trading.
all european electrical equipment is rated at 230v.
check all your stuff at home, appliances, lamps, etc

You are not making any sense
how am I wrong?
you have just agreed saying new supplie are 230
your machine 230/240 comment is nonsense

That 230 is a theoretical nonsense, they have not changed the supply voltage in this country, or any other country in Europe.

That is why the nominal voltage is 230v +10% -6%, work it out..
The voltage across the UK varies significantly, for example in Kent when on an evening they import power from France..

i agree our voltage is predominantly 240v..
i actually base all my current calculations on 240v as this gives larger current values

Looking to condition 2 D.B's which supply some box manufacturing machines (designed for european voltage).
There are 2 large P.V. arrays further down stream which make the voltage fluctuate. Voltage at the origin is typically at +240V.

Just to refer back to the OP, the issue is voltage fluctuation rather than the actual voltage.

The issue was that a voltage satabilzer was needed for equipment designed for Europe..
Further information was then provided about the equipment
a voltage stabilizer is not required

If it's just meeting 220V to 230V that is required then a transformer would achieve this.

However, there's a good chance that the machines will be fine on the UK nominal 230V supply.

It's not how I understood the OP though as it mentions fluctuations.

The issue was that the OP wants to stabilise the voltage at two DBs which are suffering from voltage fluctuations due to installed PV

That's how I understood the issue as well.
