Hi!
I would like to put the CTs into a derivation box where I have multiple electric wires.
I wonder if the vicinity of other wires can interfere with the measures or if it just needs that 1 wire is inside the CT and that's all?
What space (if any) is needed around the CT without any wires?
Thank you!
Best regards,
Camillo
Re: CT and multiple wires
"it just needs that 1 wire is inside the CT and that's all?" Generally, that is correct. There will be a very small interaction if you have another wire carrying a very high current that is very close (touching). I am testing an emonTx V3 with the standard 100 A YHDC ct and with a bundle of 20 wires carrying 5 A touching the ct (as if it were a parallel conductor carrying 100 A), it reads approx 35 W, that's equivalent to a current in a wire through the ct of about 150 mA. Moving it away to a distance of 50 mm, the power dropped to 15 W (~60 mA).
