[QUOTE="Sidewinder, post: 255091, member: 9512"] I'm guessing the power readings were with my 1ph power analyser then with the clamp on 1ph and the V probes on the other 2? I would not rely on this on an unbalanced 3ph supply as being accurate TBH. I'll have to get hold of the 3ph analyser for you I think. Canoe, does your Fluke have 3 or 4 clamps mate? The one I can get hold of only has 3, so it calcs the N current. Can't afford to buy one yet! IIRC you have loads of computing equipment, drives on the pool, drives on the kitchen extract, loads of discharge & fluorescent lighting, and tons of other electronic kit around, so, probably loads of harmonics. I suspect that the results you have are not showing the true picture due to limitations of the kit. [/QUOTE]
