Monitoring Real-Time Energy Consumption on Norax 3 Meter: Step-by-Step Guide

As in the topic, I have such a meter in the company, but I do not know how to check if there is any energy consumption at the moment. In the old meter, it was enough to look at the circle and it was already known whether a device works in the circuit or not.
Now, with this new meter, I can only read the tariff and the amount of kWh consumed.
Since I have significantly increased the energy consumption recorded on this meter, which is not reflected in the indications of sub-meters on the tenant's circuits, I want to turn off the sub-meter circuits and see if there will be still consumption, but I don't know which setting of this energy meter is responsible for it.

Here are all the cheats

In the Norax 3 meter you have symbols of individual phases L1 L2 L3 above these symbols there are small arrows, when an arrow is displayed, it means that there is consumption in a given phase, when there are no arrows, it means that there is no consumption in a given phase. Obis codes are unnecessary here. When L1 L2 L3 symbols are blinking, it means the wrong phase rotation direction, which, however, does not affect the correctness of the measurement.

In electronic counters, a flashing LED diode is an analogy to a spinning disk. The casing should be given the parameter in pulses per kilowatt hour [imp / kWh], similarly to induction meters, it is revolutions per kilowatt hour [rev / kWh].

It is also, however, when the meter has a small impulse constant, e.g. 1000 pulses per Kwh, then with a very small consumption, you can wait a long time for the LED to flash. Just the Norax 3 meter has a constant of 2500 pulses per Kwh and these arrows above the symbols of individual phases and this is how it is most convenient to recognize the consumption.

Thank you very much for the hints.
One more thing, is it possible to determine on the basis of the Codes what is the received power at the moment? - it would allow to roughly determine what device is still working.

After counting the flashes for a specific time and then converting into power (kW) according to the formula:

where:
P - power consumed in kW
I - the number of pulses per 1 kWh given on the meter (it used to be the number of rotations of the disc per 1 kWh).
i - number of counted pulses (it used to be the number of counted revolutions of the dial).
t - pulse counting time (used to be the rotation of the dial) expressed in h (hours) e.g. 15 minutes = 0.25 h, 12 minutes = 0.2 h, 6 minutes = 0.1 h

Yes, this is a code 1.7.0 P + power, instantaneous value .
Unfortunately your meter may not display much data, it depends on how it is programmed.
Back in the day, when I was doing this, I would set up the display sequence so that the most important information was available, and with a long press of the button, you could view the entire list of OBIS codes.
Unfortunately, I have now noticed that the fitters replacing the meters (subcontractors, not the ZE platform) do not have access to the meter software at all and install the one that was issued to them from the warehouse. And the codes displayed in them are completely random. It is only important that the codes 1.8.1 and 1.8.2 are available in the case of a two-zone counter or 1.8.0 in one zone.

Such a scene, a grotesque - my meter was recently replaced. I asked the fitter why the display is configured this way. After all, it can show instantaneous power, current, voltage, cosine, and even many other parameters
The answer - ladies, don't make it up, here's the first rate, here's the second, that's enough for you. And don't bother the doop, because I still have thirty meters to do today.
Curtain.

Hello in November, I have a NORAX3 counter, I have strange readings that do not match the obis codes
Code 2,6,0 shows me 7,032 Kw and the next 2,6,0 shows 13:45:00 how to read this
And the second reading is 1.6.0 Kw 2020.04.01 that is the date and time 15.45.00
My question is what is this code and why they have different values

This is the instantaneous power consumed in 15-minute periods and the time when this event occurred. After that, the collector can see if you are definitely not exceeding the contractual capacity.

Yesterday they installed Norax 3 on the plot, indications after one day 1.8.0 or 15.8.0 is over 15,000 sq m. How should I understand it, or maybe they installed a used meter?

Most likely it was mounted used. But with an important legalization feature. Check the initial condition on your next invoice. It should be written down by the installer at the time of installation. There are many used meters in warehouses that have valid legalization for several years so they are normally assembled like new.

I have such a meter, and on the manufacturer's website it says that it measures bidirectionally active power: is it true? I just have a photovoltaic plant set up, I applied to the operator for a meter installation, now I look at this Norax 3 and I do not know if they need to be replaced.

Correct measures bidirectional but no remote transmission protocol. OTUS3 meters are installed for the purposes of photovoltaics

In fact, they replaced it with a T213 with remote reading (Sagem?). I am surprised it was so fast: notification on Tuesday, replacement of the meter on Friday.

I will join the topic because I also have a NORAX 3 counter in the block with a lot of different codes, probably all of which were provided by the manufacturer.
As I understand it, to read the meters, how much total energy I pulled - i.e. what I will pay on the bill are items 15.8.0?
Now I would like to check how much at the moment, what phase, how much current is pulling? which items will these be? (because the bills have become big) Because when I understood how there are small arrows on L1, L2 or L3, current is consumed in a given phase?

If, as you write, you have all OBIS codes available, then the energy consumption by phase is here:
- instantaneous active power P + in phase
L1 - 21.7.0
L2 - 41.7.0
L3 - 61.7.0
- instantaneous current in phase
L1 - 31.7.0
L2 - 51.7.0
L3 - 71.7.0

Yes, the arrow above a given phase means that the current is consumed in that phase. Codes as a colleague wrote above.

In older electronic meters, there is a comma before the last digit displaying the counters. So the last digit is the tenths of a kilowatt hour. There is no such comma (dot) in my Norax 3 numerator. Therefore, a crowd like me states with horror that he has to pay 600 zlotys / month. Should this last digit be interpreted as a tenth of the kWh?

Rather, they are integers, not decimals. And how much do you consume, or what else you have connected and how many people, because after that you can roughly estimate the electricity consumption.

Four people: 2 large and two small. Normal load washing machine, dishwasher, induction cooker oven. Rarely 2 kW heater in the boiler, water heated from the pellet boiler. Meter installed in October 2021. There is no possibility of 5500 kWh consumption for 9 months.

I would say that 600 zlotys a month is too salty. Write down the counter for a few days at one time, you will see how much you use on average per day.

Only the question remains: why is there a comma on the neighbor's norax counter and there is no comma on mine? I called Tauron, but it was there that I found a woman who was not, no, no maize. :)

Added after 2 [minutes]:

Yesterday I only left the fridge and the consumption was 14 kWh. We checked the same with our neighbor and it was 1.4 kWh.

This would be just over 20 kWh / day. A bit much, even a lot. But if there was a comma, i.e. 550 kWh, it would be 2 kWh / day. Possible with economical use of electricity. Rather, there is a comma / period only some invisible.

I also have a Norax 3 counter and there is no decimal point there. And this is correct because in the online account I can see readings that can be seen on the meter. As on the day of reading, the collector reads a given meter reading, the same status is later visible on the invoice. So there is no comma. Of course, maybe there are some other variations of this numerator where the readings have this comma. This I don't know. Can't you put a photo of the meter with the reading shown?

In order to read all OBIS codes in the Norax3 meter, you have to long press one of the buttons (up or down), then two arrows will appear on the display under the TP and § symbols (paphragm).
For me, the counter (two-tariff) was programmed in such a way that it did not display the time codes and hours that I needed to program the timer for the 2nd tariff.

Unfortunately, it will be like that.
Recently I asked a guy replacing meters - answer:
they have no influence on what the meter displays - just as it was programmed by the manufacturer, it is released from the warehouse and thus it is mounted on the board.
Since the replacement of meters is performed by subcontractors (to whom the DSO pays per item), from now on, no one is interested in what sequences are available on the display, it is only important that the basic indications of the counters are present.

Will it be like that? So how? We have to accept the whims of businessmen?
I reported the failure of the meter, because the "lady from the window" (probably after political science) said that I should pay as it is and after the settlement period I will receive overpayment compensation.
Will it be like that? Should I credit them?

I propose to change the billing to monthly or bimonthly. He is not a fan of semi-annual settlements with forecasted settlements.

I have already decided. The neighbor has a prepayment meter and he buys electricity on a regular basis without any combination. I will try to change the contract.
