Electronic energy meters are like small computers. The need some time for starting up.
Another new test introduced by the IEC62052-11 Edition 2 is the repeatability test.
We need to figure out whether the occurring internal heat is causing a temporary error drift above the allowed limits for variation.
With publishing of the Edition 2 of IEC62052-11 the minimum run time calculation formula has changed.
The edition 2 of the IEC62052-11 has introduced two additional tests for odd harmonics.
Higher constant means faster testing. The most time-savings are coming from the no-load test and the starting test.
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
The International Electrotechnical Commission (IEC) has released the edition 2 of the IEC62052-11.
This segment of the event logs is capturing all possible meter manipulations and abnormal environmental conditions.
All extraordinary things happen inside or close to an electronic meter are called “events”. An event has at least one time record (date & time of occurrence). Some events can also have an end-time stamp.
