Hello
I just bought an N30.
I have a 3 phase (3x240V) energy system at home.
So 3 wires (L1, L2 and L3) come in with 240V difference between the wires, but no neutral.
Each of those wires has a CT clamp from KC webstore around it.
I flashed KCS v3.19.0 and ARM processor (N10203060_KU_V20_251231), but the readings show a frequency of 3x10 Hz (should be 50) and a voltage of +- 20V, one of +- 40V and one of +-30V. All three should be around 230V.
Al my fuse boxes are 2fase, so it always takes two of three available phases. The CT clamp around those seems to have good current readings.
I also have two higher load 3 phase fuses.
The fuse has 3 outgoing wires, each a phase. Each of those wires has a CTclamp around it.
In software, one is is registered on E3ch8,ch9 and ch10. Channels 8 and 10 always show 0.59A and channel 9 always 0A. When I'm using that fuse (cooking), ch8 and 10 go up and show the same value. ch9 stays at 0.
Also, like other post, Energy always 0KWh
