hi,
I want to measure three phase voltages through a micro-controller, i need 12V/2Amp input supply to my motherboard. i have decided to give the power supply from any one of the incoming three phases, say 'R-phase". whenever R-phase goes off, a intermediate circuit should transfer the...
Three phase power supply circuit for three phase power meter
Hi,
can anyone suggest me a simple power supply circuit for three phase energy meter. the meter must be able to operate from any single phase when other phases are off.
Re: AC voltage measurement using pic
hi,
if i use the above circuit for three phase measurement, how can i write the code and tell me, what kind of measurement it takes like peak or RMS or average rectified??
Re: AC voltage measurement using pic
Hi,
Can i use above circuit for three phase voltage measurement (or) tell me any changes in this circuit for three phase voltage measurement.
thanks
Hi
I am using ACS723-20A current sensor for three phase energy measurement, but i see most energy meter and pdf they are used current transformer (or) shunt resister. my doubt ACS723 is suitable for energy measurement.
THANKS
