ADE7758 frequency measurement

Good evening everyone,

 

We would like to know the frequency measuring range of the ADE7758 (Hz) because from our experiments we take valid measurements only for a range between 40 - 100 Hz.

 

In our application where we would like to use this particular chip, frequencies under 25 Hz are quiet common ( isolated small wind turbine systems with batteries banks).

 

Another question relevant to the first one is, if the sampling period is used to determine the RMS value of the current and the voltage. If this is true then we cannot use this chip to determine both frequency and voltage - current outside the above mentioned range (40 - 100 Hz)

 

Thank you in advance for your help.
