Is your electricity meter still calibrated?
If suddenly the electricity bill no longer seems to be correct, causes or even culprits are searched for. It is not uncommon for the electricity meter to come under suspicion and be viewed with suspicion. You can easily determine for yourself when it is actually time that it might have to be recalibrated.
How long an electricity meter is considered to be calibrated does not depend solely on its operating time
- Actually, the electricity meter of a household only comes into focus once a year, just then, when it comes to giving the utility employee the opportunity to do so read. If your consumption of the past year has been documented and your year-end bill has been sent to you, there are sometimes unpleasant surprises.
- If, in your opinion, the figures that are now apparent cannot reflect your consumption, you will face it Perhaps the question of whether your meter is still calibrated or it is perhaps time to have this done up.
- For all different electricity meters that record the end user's electricity consumption, one thing applies: after they have been calibrated, this calibration is initially carried out for 8 or Is valid for 16 years. However, this does not have to mean that, in general, all meters are rechecked after their deadline.
When the time for a meter series has expired is ultimately determined by the test results
- Depending on whether the calibration was carried out by a calibration authority or a test center, You will find a gray calibration sticker on your electricity meter in the first case and one in the latter yellow.
- In order to determine when the electricity meter received its seal of approval, the two-digit number at the bottom of the respective sticker is decisive for you. This indicates the year in which the last calibration was carried out. Add to the year you find there, 16 years for meters with carriers and 8 years for electronic energy consumption meters. The result now gives you the year in which the validity of the calibration should actually expire.
- Even after this time has been exceeded, the individual meters are not recalibrated or exchanged, but only tested on a random basis. This means that a certain number of counters are checked for each series that is used. If there are no complaints due to incorrect measurements in the random samples, this remains with all devices Series, the calibration is valid even if the test seal indicates a longer service life than the specified 8 or 16 years should.
- If you would like to obtain information in this case and possibly want to find out the results of the random checks, you should do so from your energy supplier. In this case, your electricity supplier is obliged to provide information.
