ade7758 avr
hi
i make it with an avr mcu and with same metering ic (ade7758)
in first step you shoud read the datashhet and define the full scale off voltage and current then choos an ct for your current sensing
then calculate the shunt resistor and voltage devider resistor
then follow...
power factor meter connection diagram
hi
claculating the best valu of t1 and t2 is dependent to best margin of the V & I please define those parameter...
Re: Energy Meter ADE7758
hi
you shod divide the reading form rms register to full scale of register then mult the result with maximom of your voltage or current.
for example max voltage of your circuite is 300v ( as vmax)
full sacle of v register is "1d38..."(use datasheet)(as fsc)
