FUNCTIONAL DESCRIPTION
1. Power Calculation
In the Application Circuit (see Figure 2), the output currents from the current sensors
will be between 0 and 16µA. The current input stages saturate at input currents
greater than 18µA
RMS
. The mains voltage (mains voltage + 15% - 20%) is used for
the power calculation, together with the current information from the current sensors
(current transformers).
The calculated power for the 3 phases is integrated over time and converted into a
corresponding frequency.
