[QUOTE="ProDave, post: 276029, member: 6969"] The trouble with using the inverter to turn on a dump load, is that it doesn't take into account any other loads in use in the house. The current transformer is this one [URL="http://www.ebay.co.uk/itm/SCT-013-030-3-5mm-Output-Split-core-Current-Transformer-/120941631017?pt=BI_Circuit_Breakers_Transformers&hash=item1c28aed629"]SCT 013-030 3.5mm Output Split-core Current Transformer | eBay[/URL] You will need to open it up and disconnect any built in components (I think there was a built in load resistor) leaving it as a bare transformer, and you build your own load resistor in when you build your own circuit. Connecting it is easy, I just used a 150 ohms load resistor in parallel with the output of the transformer, and you then connect it to any analogue input on the arduino [SIZE=8px][COLOR=#C0C0C0]---------- Post Auto-Merged at 09:52 ---------- Previous post was made at 09:46 ----------[/COLOR][/SIZE] (Having to make a NEW post due the the ridiculously SHORT edit time window) The current transformer clips around the L meter tail between your meter and consumer unit(s) so it measures all power into and out of the house, and by making a voltage measurement as well can work out the phase and so determine if it's imported or exported power.
