Hi,

I have a 16-bit sigma delta converter with 16 ksps and I want to know if it matches the single/three phase power meter.
Does any one know what much should be the resolution if no oversampling is forecasted?
How much should be the accuracy on voltage measurement? I have found requirement on current measurement but I didn't find the accuracy for voltage measurement.
How many samples should have th analog-to-digital converter?
