New Smart Meters

Lex Luthor · 2020-11-15 09:43:55

so what is the advantage for the consumer to having one of these new smart meters installed? there is some info online about the possible potential increased levels of RF that these generate down through the cabling and in the air especially close to the meter itself which has made me question the actual need for having it…

Higher voltages are better for heavy duty equipment like concrete, sawmills etc

For extremely large drives eg huge industrial mills, you have the option of things like star configuration for 400/690V (formerly 380/660V).

All of these are harmonised standards in EU/CENELEC/IEC norms.

If you go outside those you're into stuff that's not built to a known spec and start to clash with ability to get regulatory approvals for industrial equipment or components, lack of support systems : transformers, control gear, approved and tested cables, connectors, protection systems etc etc

220/380 and 240/415 are both legacy standards and in terms of old plant, your talking about an era of old national regulators and loopholes if you go back before the 1990s.

But to get back to smart metering, it will be a lot less dramatic than some of the discussions online and a lot of it may be for things like maximum efficiency car charging, which is going to become a bigger and bigger deal.
