Discuss Voltage Stabiliser in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
Looking to use the Marshall Tufflex ones. What would you recommend?
Thanks.
They market it as “cutting edge technology”, I found the same thing in a 1938 copy of Stubbs electrical encyclopaedia.
You could just use a transformer
If you're looking at voltage optimisation bear in mind that most units just reduce the voltage by a percentage. Therefore if the incoming voltage is fluctuating, so will the outgoing voltage.
They are basically step down transformers. Some can supposedly maintain a steady output voltage.
the problem with most transformers is the output would vary depending on the imput.I mentioned that in an earlier post:

thats why i sugested a ups.A transformer will not provide voltage stability. The O/P will vary with the I/P which isn’t what this question is about.
The OP also mentioned the supply is for equipment used on European system, therefore, doesn't need a voltage stabiliser
Why not?
Because, their voltage like ours, fluctuates at the same tolerances
european harmonisation
No it doesn't, harmonisation is a big myth, nobody has changed anything!
Not strictly true.. Voltage levels vary but the tolerances are the same.
therefore, voltage stabiliser not required, just a transformer
Irrelevant anyway as the kit is rated 230
No it doesn't, harmonisation is a big myth, nobody has changed anything!
Not irrelevant, the kit is rated 220 - 230V apparently and out voltage is 240 -250V in reality. But it does occasionally dip lower so a transformer would drop the voltage too low sometimes. If the machine needs a more stable supply than it has at the moment then a transformer won't cure the issue
im sorry but that is incorrect
Beat me to it Dave
wrong, the nominal voltage for new supplies is 230.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?

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

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
That 230 is a theoretical nonsense, they have not changed the supply voltage in this country, or any other country in Europe.
Just to refer back to the OP, the issue is voltage fluctuation rather than the actual voltage.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.
If it's just meeting 220V to 230V that is required then a transformer would achieve this.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

That's how I understood the issue as well.The issue was that the OP wants to stabilise the voltage at two DBs which are suffering from voltage fluctuations due to installed PV
3p motors? 3 phase?
is the 24v DC or AC?
What sort of PSU is it?
you will also find that such devices are rated at 230v, as is the same with all electrical equipment throughout the UK and Europe.
They are designed with this in mind taking into account the respective tolerances
