Hello All,
I have recently started using STM32 mcu and quite new to it.
I am developing a project in which 3-phase energy meter is needed which measures voltage, current and power of 3-phase AC signal for which MCP3903 IC is used, as I came to know that MCP3903 doesn`t provide Vrms and Irms value directly I added algorithm in my mcu but now I need to measure power( kWh) also which requires to read phase angle difference between voltage and current and I don`t know how to do it.
If anyone has already done this or have any idea how to do it please help me ASAP as my project completion date is quite near.
Thank you in advance,
