Hello, sorry for digging out this topic, but I'm a bit confused with underburden of CT:
The lowest rated power of 4NC CT is 2,5 VA, while PAC3200 is just 115mVA burden per phase, working on 5 amps. Including the burden of wires (eg. 2 meters of 2,5mm2, short distance inside a cabinet) gives a total of 0,2 VA of burden per phase. Including resistance of terminals (let's say 4 times 0,05 ohms) we would have 1,2 VA in total. That's not even close to 2,5VA. How does that relate to above quote. Could anyone explain it a bit deeper Greetings ------------------------------------------------------------------------------------------ |
