The Initial Start-Up for Energy Meters
Electronic energy meters are like small computers. The need some time for starting up.
Repeatability Test for Energy Meters
Another new test introduced by the IEC62052-11 Edition 2 is the repeatability test.
Influence of Self Heating
We need to figure out whether the occurring internal heat is causing a temporary error drift above the allowed limits for variation.
No Load Test for Energy Meters 2020
With publishing of the Edition 2 of IEC62052-11 the minimum run time calculation formula has changed.
Odd Harmonics in the Current Circuit
The edition 2 of the IEC62052-11 has introduced two additional tests for odd harmonics.
The Energy Meter Register Resolution
The main purpose of an electronic energy meter is the accurate metering of the customer consumption. The meter has registers for storing the various consumption values
Short Interruption and Dip Tests IEC62052-11
The International Electrotechnical Commission (IEC) has released the edition 2 of the IEC62052-11.
Meter housings and fixed dimensions
Recently I stumble over a request for a fixed size of meter enclosures. Tolerances have also been given with +/- 2 mm, together with features like auxiliary circuits and exchangeable communication modules.
Our outstanding customer support
With all the challenges we face during the COVID-19 pandemic, one thing always remains the same. We have an excellent customer support.
Ingress Protection against Water and Dust
In many regions of the world the energy meters are installed outdoor. They are exposed to various climatic- and weather conditions.
