* What lifetime do you expect? Many, many, many industrial equipment use optocouplers and have a 24/7 lifetime of 20..50 yearsWhat I didn't want is use opto acopler because it hasn't a long life period and as every semicondutor it has a little distortion and the transformer as it follow the faraday law, it's has a non plane frecuency response.
I want to sense with the ADC the signal to make the FFT to measure the power factor, taking in care the THD. The current would sense with a hall efect sensor.Are you talking about a digital (e.g. voltage presence or zero crossing? detector or an analog voltage measurement. An standard opto coupler isn't suited to isolate analog signal without modulation (e.g. sigma-delta, V/f, serial transmission of ADC data).
