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 . The mains voltage (mains voltage + 15% - 20%) is used for

RMS

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.
