Hi, i am using 3 of your SCT-013-000 already in my home energy monitoring system. for a second project i need to measure wires of 15mm diameter, and the SCT-013 is too small for that. can you supply the SCT-019-000 of YHDC which has 19mm diameter? Can it come with the same mini plug?
Hi
I know that the SCT is designed to be used with a split core - i.e. I need to run only the live wire through the aperture. However I'm thinking about a novel application which relies on detecting power in a kettle flex. Basically I'd like to clip something like the SCT to an unmodified kettle flex and be able to tell whether the kettle is on or off. I don't need accurate current readings, just a yes/no answer.
I believe that if the kettle flex was perfectly symmetrical this wouldn't work, because the magnetic fields in the live and neutral wires would cancel. However a real flex is not symmetrical - the two wires are offset within the core.
Can the SCT detect current in these circumstances?
it is an abnormal SCT application. just tested by the air conditioner in office, seems their would be some output from the SCT... can not ensure if it works with the your "kettle".
Hi what is the maximum cable length that can be used with this to link multiple PV inverters together to monitor the outputs from both Both CT sensors will be used in Arduino based open monitoring system to read power production against grid usage
If you choose the current output one then a very long cable length can be used (many tens of metres). This principle is used in 4-20mA loop systems. Just provide a suitable load resistor at the Arduino end.

Hello, thanks for your interest in this product. We are only the distributor for this product and we do not much about its technology, thanks for your understanding.
I had the idea to use the current output type of this to directly power a microcontroller with a backup battery. So I can clip it on the wire and forget it. Later I get the SD Card to look at my consumption. This is for inductrial use, so I will have at least 10A (more likely 50-100A) on the primary side. on the secondary I guess that 0.1 A would be far enough to keep the logger alive.
What do you think? could this work?
Hi Alexis,thanks for your questions. We can not ensure that because we haven't try to used this product as a power .
Works well so far (played with it for a couple days so far), but the spec sheet seems to be off. The English version says the output is 33mA output current per 1 amp through the CT; the Chinese version says 50mA per amp; my actual measurement on 2 units is approx 6mA per amp (approx because I don't have a ammeter that goes high enough). Calibrate your units before use, your mileage may vary, ...

Hello,
I am interested in the SCT-013-000 current transformer but I don't know which is the wire it uses to connect to the PCB.
Do you know which wire is and which are its features?
Besides, I am also interested in knowing which connector is needed to connect the Current sensor with the PCB and how is the signal that arrives to this connector from the SCT-013-000.
Thank you very much in advance,
Best regards,
Lucía
