ADE9000 Schematic / FW Mods for Motor Drive Analisys (3000Hz)

on Jul 17, 2018

Dear Sirs

We´re succesfully using ADE9000 IC for Three Phase + Neutral AC Mains Analytics @50Hz in our industrial Machinery

Now we need to use the same PCB we´ve designed also for measuring AC Motor Drives Phases (Without Neutral) @3000hz

I need to know what FW/HW modifications should we perform in order to get the best measurements

I will pass schematics if needed

Kind Regards

    Hi nacho,

    What is your requirement accuracy?

    ADE9000 cannot monitor fundamental components of 3000 Hz, those values outside 45Hz-65Hz will be measured as a harmonic content. 

    You can use ADE9000's waveform sampling and process it to get energies up to 3000 Hz, so you will not utilize the chips metrology engine here. You can also use ADE7880, it has a harmonic metrology engine. But it is not an optimized fundamental energy measurement, however if your accuracy requirements will pass, then it will be okay.

    Thank you very much.
