The 2020 End of the Year Riddle
Before we come out again with interesting and metering related topics in the next year, please take a look at our brain-teaser quiz.
Laoren is the Chinese name of Reinhard Günther.
He is Product Director and Consultant with more than 35 years experience in energy metering. In his spare time he writes articles for CLOUGLOBAL.

Table Tennis (Pīngpāng qiú 乒乓球) is one of the top National sports in China. As a proof of concept we have remade a very old arcade game.
You can find this term in a lot of technical documentations with more or less complicated explanations. We’d like to give some simple examples for the need of hysteresis in energy meters.
The end-user had an energy meter with rotating disk (electromechanical). These meters are usually already in the field for more than 30 years.
I recently stumbled over some advertisements related to plug-in or paste devices which are claimed to reduce the electricity bill by an average of 10%.
DTS719 is a transformer-operated three-phase smart meter with an embedded radio-frequency (RF) solution for local access.
By now the UIU / CIU short-codes are not unified. We have collected and merged all recent requests.
CLOU energy meters and test equipment is measuring the true RMS value by waveform sampling. There are other methods, but they are less accurate.
With increasing percentage of renewable energy on power generation we will see more disturbances in the grid.
The interactive graphics below shows the impact on sampling rates on different waveforms. The error calculation is based on true-rms for a wave with 360 samples and for training purpose only.
