The AI Energy Meter HF can be used in TN, TT and IT systems.
Measuring with AI Energy Meter HF
A typical supply network of a production plant is usually divided into three voltage ranges:
● The infeed of the entire plant
● The subdistribution, for example, to individual lines within the plant
● The end consumers such as the machines in the lines.
The following figure shows the measurement in an electricity supply network:

Advantages of the AI Energy Meter HF
The AI Energy Meter HF has the following advantages:
● Space-saving especially for use in control cabinet
● PROFINET IO or PROFIBUS DP (depending on the interface module in use)
● Multiple modules can be used with one interface module
● Extension of existing stations by components for energy recording
