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 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.
