[PIC] 3 phase vaf meter.....

[jit_singh_tara]

Dear Friends ,

I want to make 3 phase v,a,f meter with ct 5amp secondary winding rating .
Has anyone tried this kind of design .I need true rms meter .I will prefer microchip but any other mcu is also not an issue ...I have seen some meters using texas or renesas 16 bit mcu .Can we make it on 8 bit mcu .
Please share the design ideas .


Thanks and regards
Jitender.

ADC resolution affect ur accuracy. If u require good accuracy than use more bit but at same time ur require good controller having high speed ADC with simultaneous sampling, good floating point data support.
Plan ur specification than make paper work to select controller
