What you starting to believe me that maybe, just maybe micro-generation may increase local grid voltages??

This is a paper from the ENA to the DNOs, and I quote " localised penetration of micro-generation may give rise to localised voltages exceeding statutory limits and even operation of G83 protection. The ability to monitor voltage profiles and even utilise this information for active voltage...

Seems to go against everything we been debating about over the last couple of hours, BTW the ENA released a report on increased voltage levels due to PV installs and recommends inline voltage regulators as one of the solutions :Blushing

Why are they set at 262,2v, surely this is potentially detrimental to CENELEC limits, this is a question not a statement

Sorry :Salute

OK got one Guinness Canoeboy I just asked you a question in another forum which is probably in the wrong place, I thought G83-2 settings are also 262v

No Noz, the point I was making was that the higher the voltage the hotter the charger gets Canoeboy, I thought G83-2 settings were also at 260v trip settings??

Gees guys I am not getting enough breathing space to go and get another tinny :)  

Andy, the total output needs to be closer to what it is designed to run at, you say that a light is dimmer with lower voltage but also a light is brighter with higher voltage, your argument on getting a lower powered light is a bit topsey turvey. If you buy a 60 watt light then why would you...

Then we will have to agree to disagree, as the grid voltage will rise with a fixed impedance, also the voltage will drop on the other 2 phases in the street if they are imbalanced, and their impedance is also fixed!

Yes Noz it only gets warm when it is charging!

As am I, I would be interested in hearing your educated opinion on why VO doesn't work?

Actually Jono the average UK voltage is 242v, but in some areas include mine in the midlands we are closer to 252volts, trust me my iphone charger gets very warm on a night time

Sorry you are looking at it the wrong way, yes the grid has a fixed resistance applicable to the localised area, when you connect a load onto the line the voltage will naturally drop, now if you inject further current into the line you will raise the grid voltage. Have you ever thought why we...

if you get chance to have a look at the electricians guide to the 17th edition by John Whitfield I think, it gives you a few worked examples of 230v equipment on a 240v supply, also an explanation on our grid voltages remaining high in the UK, its on about pager 7 I think

Thanks for the responses guys, Yes I am in favour of Voltage Optimisers but not just on the energy saving side (which it does) but also on the safety side on preventing appliances made for Europe and rated 220-230v and exposed to our all to frequent 250v. Anyway onto the original point, are...

OK Guys,please ask yourself the credentials of an article that states a house pfc unit as a voltage optimiser (item 1) any engineer will know that reactive power is not charged for at a domestic level. Onto V-Phase, this unit was good for a standard running load of 8 amps (VX 1), technology has...

Hi all Quick question on G83-2 Voltage levels from a VO guy. Under G83-2 Voltage levels for stage 1 disconnect of inverters are allowed to be up to 262volts, do you feel this will have an impact on surrounding properties on the same connection point, taking into account that house hold...
