Discuss Voltage optimizers any good? in the UK Electrical Forum area at ElectriciansForums.net
Thanks. I've since done a bit more reading. According to this report they save you about 6% a year. >> https://www.ofgem.gov.uk/sites/defa...-saving-trial-report-for-the-vphase-vx1_0.pdfThey work in so far as they reduce the voltage, they don't work in so far as they don't reduce energy consumption by any appreciable amount.
I have fitted one of these voltage optimiser/stabiliser units in a situation where the incoming supply voltage was sitting at 250V and the installed equipment was designed for 230V and was regularly failing due to the over-voltage.

I wouldn't bother there are too many variables to create an exact same useage profile over two 3 month periods, I would think even doing it under laboratory conditions would prove difficult to replicateIf you install one, please wait for 3 months, have some good evaluation of the consumption and then do an identical evaluation for 3 months afterwards and post the results here, it MIGHT be the first real life proof that they save energy!!
How was this measured though? I wouldn't trust simple meters as the sine wave is often distorted by harmonics and the rms calculation might be inaccurate because of it, I assumed if it was out of tolerance ukpn would sort it. Do you have solar and was the voltage causing an issue?I have one installed without it I had 258v come through the sockets and with it I get 220v, I've had it since 2015 I've had no problems with it at all.
That is a use-case where they make sense, although 258V is out of the ESQCR range of +10%/-6% on the nominal 230V (rule 27.3b) so it should be corrected anyway:I have one installed without it I had 258v come through the sockets and with it I get 220v, I've had it since 2015 I've had no problems with it at all.
I don't Have solar just a two bed terrace house in town built in the 1800sHow was this measured though?
