Smart meter diatribe

Legh Richardson
What does the panel think about this?

Smart meter scam?


I'm interested in a professional qualified view as this character is pretty ruthless regarding the energy suppliers

    Quelle arnaque !



    Apart from seemingly not really understanding VA and power factor, I think what he's really trying to say is that the smart meter is enforcing the limit at something like 39.1A (which more closely matches the agreed limit) rather than the 45A the old circuit breaker supposedly tripped at - i.e. he's lost a bit of unofficial leeway.


    Well now, I don't think that he knows what he is talking about.


    The devices in question (disjoncteurs de branchement = connexion circuit breakers) are RCBOs. The RCD bit is usually 500 mA type S, which provides basic protection on what is normally a TT system. I have been unable to find any trip curves for the MCB part, but presumably they do not trip the moment that the setting (which could be anywhere from 15 - 60 A) is reached. Surely, they must allow for a degree of diversity.


    As for where have my kW/kVA gone? The 15 / 30 / 45 / 60 A settings are equivalent to 3 / 6 / 9 / 12 kVA nominal, so nothing has changed there.


    Whether the smart meters have an overcurrent interruption capability seems very questionable. It also appears that they do not transmit instantaneous consumption data.


    So what we have is another diatribe which has no basis in fact.
