Sorting out an Australian three-phase installation


#21

I don’t know about Mac. The advice you got on that was from someone who has done this before successfully. It is just a 115200 baud serial terminal plugged into the iotawatt USB connector.

The latest ALPHA that will go out today has code to minimize the hanging when this occurs, but the doesn’t address the underlying problem that I believe to be your VT or the circuit it is connected to.


#22

Ah yes sorry, I forgot that the Silabs USB UART driver is not included with OSX by default. You can download it here: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

@overeasy I have modified the bulk upload to 6 and its working/recovering so something with WiFi interference that I will have to trouble shoot. I will get you logs in the next 48 hours.

I did notice this on the Web Server Screen - is the date corrupted or just how it represents earliest available? The actual logs etc are all showing correct dates.

Notes:
-I changed to ALPHA and restarted yesterday morning around 9:30.

-we have no missing data from last night for the first time on eMonCMS

-Log files are a bit messy around 14:00 as I rebooted a few times to ensure all was working and we were actually capturing/logging to disk. I have posted both the log from emoncms web server and serial capture.

-The voltage seems to drop to 0? When this starts to occur is when the house gets some “flickering” in the lights so it might be a mini brown/black out but its for a fraction of a second. This is the first time we have actually seen it in the graphs (as the unit hasn’t hung).

-There has been no intervention on my part with the IotaWatt power/reset/network etc.

-I have ordered a second iotawatt from UK with 2 x VTs (that way the VTs will be identical and if there is an issue with mine from JayCar then it will get resolved)

-I will update my post in an hour or so but the totals logged by emoncms for kw/d feeds seem almost exactly 50% higher than the meter reading for Mains. Solar is correct.

Graph of Voltage from IotaWatt:
(This matches emoncms and I cant see any missing data points on either of them after than the reboots at 9.30 for ALPHA and 14:00 for logging)

CSV Output from Graph.

#25

That’s because of the change in 02_03_12 that eliminates the hang.

That’s new. Don’t think the flickering was mentioned previously. The graph is plotting average voltage over 120sec periods. When it goes to zero that means zero for two minutes. Those other dips down to 200V are probably the result of dips to zero for just a few seconds. You might want to take a closer look at that by zooming in to 10 or 5 second intervals. Might be interesting.

So you apparently have a poor power supply. Could be a bad connection on your property, or it could have something to do with the local distribution system. It’s odd that it happens around the same time every day. Unless you have something coincident with the problem on your property, I’d start to suspect the grid.

When you get the new IoTaWatt, it would be a good idea to spend a day or two monitoring the voltage on the other two phases.

Id like to see the numbers for the mains, meter, and solar. I have a hunch.

Also, could you do a daily plot from IoTaWatt of power on Mains1, Mains2, Mains3, and Solar. Plot them all on the same scale (left). 50% is a very suspicious number when dealing with three-phase power.

It’s odd that it happens around the same time every day. Unless you have something coincident with the problem on your property, I’d start to suspect the grid.

We are very close to both a small “Country” Shopping Centre (Full size supermarket/freezers/aircon etc.) and a few sports fields (large lighting etc.)

Power flickers at same time every night - could be local mall freezers or lights firing up but haven’t got a better handle on that yet. The IotaWatt was also connected to a Laptop last night so it would have had battery which might have buffered out some of the Power Supply spikage though I think it was your fix that let it stay up.

We do get resets - eg the Playstation will drop at that time and while we had suspected a rebuild of it was in order its getting to regular.

Some Graphs for your pleasure.

I am wrong about 50% but its still reading high for Mains (eg Metered 54 vs 67, Metered 44 vs 92).
We really need another few days as the read time needs to be 10:00 to be in line with GMT which is where eMoncms calms the kwd

**EDITS: Update Meter Read Daily…


#27

So… We had a flicker around 17:40

You can see in this graph that Phase 1 goes away for a bit and that coincides with the voltage drop.

I have mapped the 3 phases out. The power spike is the aircon (3 phase) and hot water unit (Mains3) firing up.

While we get a flicker in the lights, I don’t think we lose power for anything more than a fraction of a second. I am suspicious that the other Mains Phases read as a undulating flat line…

[/quote]

Define flicker. The IoTaWatt shows an outage for ten minutes. If your lights were on during that time, IoTaWatt could not find a symmetrical AC cycle to use as reference. In any event, it logged zero (I believe on all phases, those lines are just the graph utility filling in the gap with the last known value.

So the changes to the sample routines are now picking up the problem and handling it as best it can. I don’t believe this is related to your problem of not matching the meter.

I think I’ve said before that there are a lot of different combinations of phase assignment and CT orientation. I think it’s 48. So there are 47 different erroneous combinations, and 1 correct one. If you have all of the CTs oriented the same way, that reduces the possibilities to 12. If you are certain which line has the VT, the possibilities are further reduced to 4. 3 incorrect and 1 correct. So lets take a look at that old picture of the back of your panel. I’ve marked it up with some labels that I believe are correct:


I’m not sure if this is still the way you have the CTs. The picture is from August 4. I’ve added arrows to each of the Line and Load cables that go to the fuses. Assuming an arbitrary direction of into each fuse, it goes through the fuse, then out the load cable to the meter. So the CT labels on Line A and Line B both face the board. Lets go with that. Now, looking at the CT that you have placed on Load C, the label also faces the board, yet the arrows on the load side point away from the board. So I would say that the CT in the picture on Load C is backwards. Going by the same logic, the CT on Solar is also backwards, but by convention, we usually want the solar generation to be positive, so to get a positive number when current flows backward through that line to the fuse, you should leave the CT backward as is.

Now this is going to change the measurements, exactly how I can’t say. Also, it’s possible that the phases are not correctly assigned. Thinking this through, and my head is starting to hurt because this is not my area of expertise, but remember that I said that if all of the CTs are oriented the same way, and we absolutely know which one is the VT line - phase A (by definition), then there are just four possibilities:

  1. The correct one.
  2. The inputs are assigned to the correct phases but all of the CTs are reversed.
  3. The inputs assigned to phase B and C are reversed and all of the CTs are correctly oriented.
  4. The inputs assigned to phase B and C are reversed and all of the CTs are backwards.

I’m not sure if any of our previous observations can eliminate any of these possibilities, but until that line C CT joins it’s mates with the same orientation, there are a lot more possibilities. So what needs to happen is to insure that all the CTs are oriented the same, and we’ll proceed from there.


#29

Thanks for the detailed approach - lets work through it

Define flicker

The lights (which are multiple 5W LEDs eg x4 or x6 (equal to 100W old style bulb) flicker for a fraction of a second. That said its enough to make a Sony Playstation 3 reboot or if it was off start up. Normally we get about 3 over a 30 minute period.

I haven’t ruled out the air con pulling a lot of power and browning out as it seems to ok when both aircon and hot water are running (all which use PhaseA) but I suspect its the main circuit coming in.

If you are certain which line has the VT, the possibilities are further reduced to 4. 3 incorrect and 1 correct. So lets take a look at that old picture of the back of your panel. I’ve marked it up with some labels that I believe are correct:

The picture is current state and I am 100% positive that the CTs for the Main Phase inputs (Line A,B,C) are oriented the same way. I take your point re load vs line so we should look to move it. Alternatively I can move A and B so we get loads vs lines which might be more consistent.

My plan is to hold off at this point as its now dark outside and I just had tried the sauna for the first time.

Plan Step 1.
I am going to disable all other circuits and get you a shot of IotaWatt with the dryer operating plugged into the same power point as the VT so we can start with that.

I think we should also get the Mains CTs on LOAD for each rather than line but I will await your advise.

I really appreciate the input and will check the board / todo list methodically tomorrow and will report.


#30

I spent quite a bit of time putting together that annotated picture, explaining the reasoning, and presenting a way forward. If you are 100% positive your orientation is nevertheless correct and want to do something else, I cant help you any further. Best of luck.


#31

Please don’t jump to conclusions - I was tired when I wrote that but lets break it down.

The picture is current state and I am 100% positive that the CTs for the Main Phase inputs (Line A,B,C) are oriented the same way. I take your point re load vs line so we should look to move it. Alternatively I can move A and B so we get loads vs lines which might be more consistent.

This is a badly worded question on my behalf. So lets fix that.
The picture / labelling is great and its a useful reference point going forward.

As can be seen in the picture the CTs for the Main Phase Inputs (A/B/C) are all oriented the same way and of that I am sure. I never said that this was the correct way.

My query came from the good point you made of line vs load.
Mains A and Mains B are plugged into the LINE and Mains C is plugged into the LOAD.
This means that one set is wrong and I am assuming its line C you wanted me to move but it wasn’t clear to me last night as the other option was moving A and B over to LOAD so that everything was consistent.

I think my next steps are:

  1. Shut down other house/3 phase power users 3 phase and run a load to confirm the phase that the VT is plugged into and take a screen shot.

  2. Reverse the CT for the Mains 3.


#32

I have done the following and await further suggestions.

  1. Re read and applied your directions above and referenced this thread.
  2. Moved the CT direction on Mains 3
  3. Turned off the big 3 phase consumers at the breakers (Aircon/Shed/Garage)
  4. Run the VT / Circuit test with hair dryer (results below).
  5. enabled the hot water (its now showing backwards which I can fix later but I think pf is good…)
  6. I am still logging at 10:00 and capturing stats

Please let me know what you want me to do next.

Again thanks for all your help.

I will figure out Garage3 Later… Its breaker is off.

OK, here’s what concerns me now:

  1. The water heater is showing as 3017 watts, yet the main that feeds it only shows 2671 watts. I think the phase is correct as indicated by the power factor being unity, so I’m questioning the CTs. Obviously the CT on the water heater is reversed, but I don’t think that should be a problem. Here’s what I’d like to do:

a) examine the nameplate of the water heater (a picture would be best). I’m looking for the watts and voltage specification. If it has multiple elements, try to get all of the information on each element.

b) exchange the CTs currently being used for Mains3 and the HotWater. That is to say physically move the CTs, moving theCT to the other circuit and the plugging them in to the other input. If it is a CT problem, the problem the MAin will become overstated.

c) Install the CT on the HotWater reversed from the present install.

  1. The 1300 watt hair dryer appears to be drawing 1500-1600 watts. I’d like to validate that. If you can put together a few incandescent lightbulbs (remember those?) and plug them into the Mains1 circuit, noting the total wattage of the bulbs and the differential as you switch them on and off.

Lets see where this leads.

HWS - Solar component Stats
This is the solar component of the of the hot water service…
I have included it for completeness but will need a second body to help troubleshoot/trace the wiring as I don’t know how its actually powered and that will be a voyage of discovery.
I can see a line from the the HWS Circuit breaker on the Main board to an external power point with 2 sockets and both the HWS unit and the roof are connected to it but it does continue to make power even with the HWS circuit breaker off. Previous owner only used to switch it on the HWS Booster circuit breaker during winter to save costs.

HWS - Booster Stats
This is the one we need to look at and what kicks in to boost as needed.

b) exchange the CTs currently being used for Mains3 and the HotWater. That is to say physically move the CTs, moving theCT to the other circuit and the plugging them in to the other input. If it is a CT problem, the problem the MAin will become overstated.
c) Install the CT on the HotWater reversed from the present install.

Method.
-removed both CTs from wiring
-swapped the inputs (3 & 5) on iotawatt
-reconnected as suggested (reversed).
Note: I also disabled solar (isolated at the solar board) as I wanted to see if it was making any difference (as its on the same Mains 3 phase. It made 0 difference).

Updated Screenshot after CTs between Mains 3 and HWS moved:

The 1300 watt hair dryer appears to be drawing 1500-1600 watts. I’d like to validate that. If you can put together a few incandescent lightbulbs (remember those?) and plug them into the Mains1 circuit, noting the total wattage of the bulbs and the differential as you switch them on and off.

The hairdryer stats I think we should take with a grain of salt. I did some googling on this which is the model “babyliss super turbo 2800” and got stats back from 1300-2000W with most of them stating 2,000w even though the original paperwork said 1300. While its probably a good load test to see if we have phase correct, its probably not useful for accurate measurement of watts.

Lighting options.
Your suggestion might This may take a little time as I need to find some incandescent bulbs and work out a method to get them into the Mains1 circuit as the lights are on a different circuit/phase.

I do have a portable floodlight which should do the trick - its got an incandescent 150W bulb and a standard aussie power point so I can move it around.
Question - can I use the 150W portable floodlight and get you before/after shots?

I like that the Mains3 is now more than the HotWater heater, but the nameplate on the WaterHeater says it should draw 3600W.

That should be fine. Can you try plugging it into various places and switching on/off a few times (leave on for 30 seconds or so then off for same. Then plot your three mains for that time period with 5-10 sec resolution and post.

Thanks.

Agreed - possibly a bad CT - possibly an older heater - there is another IotaWatt and 10 x SCT-013 coming but at this point I would almost be happy to be done with it and replace them CTs you like/recommend (I know there are some smaller units and as I don’t have large cable and its a bit tight this could be a better option. If we need to go down that path then I am open to it.)

This I can do.

Questions:
a) do you want Phase A/B/C Voltage on the same graph or just make graphs with the one phase thats getting the load?

b) Please explain what you want by “5-10 sec resolution”.

I am assuming you want something like this graph but with it marked up so you can see where I have added 150W to each of the circuits?

I am guessing that the Fixed Interval is what we want. It took a bit for that to work as it didn’t always update the graph for me - I had to flick the “missing data” toggle on/off to get it to re-draw.

Not to go off topic but with what I think is a resolution of 5 seconds you can see the typical voltage sag we get n the graph below - its not 0 but around 175v which is a brownout for sure.

They are pretty regular - 5.30pm, 6.30pm, 8.30pm every night - its not the air con as you can see it in use then stop


#38

Yes. Mains1-3 without the voltage.

Center the area of interest using the “<” and “>” buttons at the top left and zoom in with the “+” button. I don’t know what happened with the graph you posted, but the “Fix” and “Limit data interval” boxes are checked and the resolution isn’t very good. Here’s what it might look like:

Most of those spikes are a fishtank heater with an overly sensitive thermostat. Og course you will have three traces.

I should be able to see it without any markup.


#39

Here you go sir.

Method was
a) turn off non essential power to reduce any base load - I cant remove all of Mains A though as we need internet/power/etc but at least it should be relatively constant.
B) test to ensure I had the correct A/B/C then wait a few minutes.

Then (waited to 13:41)
c) Plugged into Mains A for 90 seconds
d) disconnected for 60 seconds while I went to Mains B then rinse and repeat.

Added an additional Graph - Mains 3 - shows 140w for the light when plugged in. That said its rated as 150w. As far as I can see this is consistent on Mains 1 and 2 but harder to show as we have other power on at the moment.

A random shot with many things happening. The mains look good but I have no idea what is using that much power in the house…unless the mains is reading way high.

That said things aren’t 100% looking at the pf
There is another unit/CTs on its way and once we are happy with the mains I will start connecting the others up. At least that way we will have measured feeds vs the calculated one so I can do some detective work.
