    Quick tip for those who don't like guesswork. Calibration can be sped up a lot. If you have say 0.32A and expect 0.50 try 0.5/0.32*current conversion factor (like 10000 in the video). You'll get 15624, close to his final 15420. Like mentioned, higher current loads will yield better results using this same process

    Starting with a value of 10000 and the known amperage, we can find the calibration value using the formula (10000)(amperage)/(indicated value). For your example (10000)(0.49A)/(0.32A)=15312. Hope this helps!

    @amisakie 5 лет назад +5

    Great video. You can trick the clamps into thinking that they're is more current if you loop the wire back around and through the meter clamp. So if you had a 10A load with 1 wire through the core if you wrap it around and bring 2 wires through it will read 20A.

    • @teddyruxpin3811
      @teddyruxpin3811 Год назад

      why would you want to do that? Would that be a way to measure two lines using only 1 CT clamp? So if I wanted to measure a 220V circuit like in the USA (which is basically just two separate 120V lines), I could put the clamp around both wires and it will automatically add up the amps and watts?

  • @fredflintstone8048
    @fredflintstone8048 2 года назад +3

    In many applications disconnecting a CT output wires will cause it to burn up, or to damage the insulation rating of the secondary windings by causing the voltage to rise too high on the secondary winding for what the secondary wiring insulation is rated for, ruining the CT. Always keep them connected when current is running in the wire they're connected to for sampling.

  • @TrentSnyder308
    @TrentSnyder308 5 лет назад +7

    Easier way to zero in on the calibration: correct multiplier = test_multiplier * expected_amps / measured_amps. For your example, 10000 * 0.49 / 0.32 yeilds 15469. (I love using math to short-circuit iterating.)
    The ratio of the correct multiplier to the correct amperage is the same as the ratio of the test multiplier to the test amperage:
    M[act] / A[act] = M[test] / A[test]
    x / 0.49 = 10000 / 0.32
    Solve for x.

    • @TrentSnyder308
      @TrentSnyder308 5 лет назад +3

      This does assume linearity of the system, of course. If a system isn't quite linear, it should get you close, then you can iterate. Since these CTs should be linear, one sample should get you spot on.

    Note this: When you put hot and neutral wires through a ct, your current reading should be 0 amps on a 2 wire circuit. (aka this how GFCI works through a ct inside the device or breaker) If you clamp an amp meter on the neutral and then clamp it on the hot of the same circuit it will read the same. When clamping both Hot & Neut of the same circuit value will be 0 (balanced)
    If your clamping it on a 3 wire circuit where the neutral is shared, your reading will be the different or the unbalanced load of the two circuits or if both hot's have the same type of load L1 = 1500W (Black) L2 = 1500W (Red) then 0 watts 0 amps on neutral (White)

    going to set it up as zero balance grid connect system, put enough power back into the grid to cover the losses during cloudy days and nights if all goes to plan.

      Anyhow...This afternoon got the ESP32 programmed and installed on the main "meter board." Everything is working fine, but now I need to do an accurate calibration on the CT's.

      One thing that got me was the CT's for my "mains." The CT's I bought (from the same website) were too small to fit over the wires, so I ordered 2 of the clamps (from the same place) with 16 mm opening. They were STILL too tight, so I used a rasp to remove a bit of the plastic in the opening. They still wouldn't snap completely shut so I tightened them down with some zip ties.
      So if you want to monitor your Mains lines, I'd suggest finding CT's with 18 mm opening if you have large wires. :-)

    sensor:
    - platform: ct_clamp
    sensor: adc_sensor
    name: "Measured Current"
    update_interval: 60s
    filters:
    - calibrate_linear:
    # Measured value of 0 maps to 0A
    - 0 -> 0
    # Known load: 4.0A
    # Value shown in logs: 0.1333A
    - 0.1333 -> 4.0

    Just picked up one of the "split phase solar" that comes with 2 X dual channel monitors and the board they connect to with the ESP 32. Been working on the house and upgraded the panel so figured may as well have good monitoring. Planning to do some grid tie solar as well after I get the roof replaced and some other stuff done.
    Anyway is there a major difference in how the boards will work compared to the single 6 channel version? I will end up with 4 channels total with 2 voltage channels. My end plan is to throw a 220 breaker into place for the solar to feed in on as I plan to install the panels and grid tie inverters in pairs to be able to use them for 220 appliances along with 110 stuff. And the goal is to be able to island during bad weather if needed using a small 220 generator to provide some basic power and allow the solar to take up the slack during the daytime (yes I plan to isolate from the grid when I do this for safety).
    By default the board comes with EmonCMS component installed but I don't want to use something else in between the HomeAssistant install to deal with the data. I really want to use ESPHome since I already use it quite a bit for things anyway but kind of getting in over my head with the software setup on this. Looked at the info on GitHub that you have posted and right now I'm not exactly sure what I will need to do. Hopefully everything will ship out and be here sometime next week but going to setup another ESP32 I have now to get started.

      The 6 channel has two of the 3 channel ICs on it instead of one. The board actually doesn't come with any software as it does work that way. The ESP chip that is connected does all the WiFi/CPU stuff and you can put whatever software you want on it with a simple USB cable.

    A critical aspect of this is the non-linearity of the CTs. Unless you are operating in the ‘sheet spot’ of the CT then non linearity will be an issue. Do you know if the chip somehow corrects for this? If so how does it do it as I did not notice you characterising each CT for its linearity.

    I'm not sure if I'm missing something, but wanting to do this. When clamping both lives in a split 240v system and then adding them together you get the total amperage from all of the 120v breakers, but wouldn't it double count any 240v appliances? My theoretical solution to overcome this would be to measure both lives and the common. And then do something like (L1 + L2 - Com) / 2 + Com to get the total current. Am I missing something obvious and it can be simplified? I know this is an old video, but thought the people here may be able to help.

    I am wondering if the board is accurate enough to... Instead of adding SCT clamps to other circuits only clamp to the main input and develop signatures based on voltage changes for other devices coming on and off. For example. The dryer draws xxxmA and if you detect a change in voltage of xxxmA the trigger automatons for your dryer. Fridge draws xxymA, bedroom fan yyymA, etc...

      I don't know for sure, but I would not think so due to the following. It would take less energy to reach the temperature set on your dryer from summer to winter because of the air temperature. Also if you ran two loads back to back the air temperature would be different, so the drier would not have to work as hard. But that's just my guess.

      You could figure out what is what if they are inductive and resistive loads. The metering ICs figure out reactive and apparent power. So you could, for example read the "signature" of you electric dryer when it is on. Reactive power will be low (apart from the motor that spins the drum).

    In my esphome configuration, I use power function and power template which P = Volt*Current to compare the watts value. The power has about the same value when the load has less than 100 watts or over 1200 watts. if the load between ~100w to ~1200w, the value in power function always has about 50-150 watts less than the power template sensor.

    digiblurDIY,
    Very nice video. In using your YAML file, I got voltage readings of 655.34998, which is suspiciously close to 65,535. I had to scale my voltage gain figure down to 7478 (for a 120.7 VAC reading), which may be due to voltage divider changes in the version I have. Using v1.3 of the 6 channel energy meter board, 9 VAC Jameco transformer, and 100A/50ma clamps. I will have to read through the comments below to get watts directly off the board instead of calculating it. Thanks again for your work

      I'm not familiar with using it on 3 phase but I would assume you could just put the clamp on it and go? Of course you could have the voltage differences. Might be a good question for the CircuitSetup folks.

    • @jdeg2000
      @jdeg2000 5 лет назад +3

      The ICs are actually made for 3 phase. However, the 2nd and 3rd voltages are not hooked up. You can get around this by writing to the B and C voltage registers. From what I can tell esphome cant do this yet, but I may figure out a hardware solution for the next version.

I then deleted and re-entered all and it worked for a while and then I am back to no route to host when trying to update the code. Maybe it was a defective module. I purchased two and the 2nd one worked with no issues.

    Great video - thank you! Regarding the warning about unplugging the CT From the board - I want to make sure I am understanding (sorry if this is a dumb question) . If I unplug the RCA plug from the board the tip could be dangerously energized? Is that correct? Would this be for all CTs or is their a certain CT I should look for that would reduce or eliminate this risk. How would you safely unplug it from the board? Thanks again!

    • @AnilGhatikar
      @AnilGhatikar 5 лет назад +1

      Yes All CT's by deafult are dangerous when the secondary is not connected to load or short circuited. To understand imagine a ct of a ration of 200 to 1 ( 200 primary amps results to 1 amp on secondary) so when open circuit CT will amplify the 100 V on primary by 200 times .

      @digiblurDIY  5 лет назад +1

      They can be used safely if you just take your time and go through the motions. The YHDC models I used either have the zener diode or burden protection circuit in them. To prevent any danger. Remove any load from the circuit first then you can unplug them. Do not turn the circuit back on until either the CT is removed or is plugged back in the board.

      You could use those 220 channels to monitor anything you like. Keep in mind that US 220v appliances would need 2 channels to capture the entire usage. You could do the entire house with 2 channels but it wouldn't be broken down. I use the 6 channel where 2 do the entire house then the other 4 are broken down to other circuits.
