Is there any code examples to get an arduino or rasbery pi to do the math required for symetrical components calculations, and also KW and PF calculations from voltage and current inputs.
I am trying to make a networkable power meter. Sq d is charging 5K for one in a switchboard and although the Potential Transformers are 76 bucks each and the CTs are 180 bucks each, that leaves a lot of margin on the circuits and code on the meter.
I also have protection relays that use they symetrical components to determine faults and classify them. They also have the ability to determine over current situations depending on power flow direction.
any help is appreciate on the code side. Getting the voltage and current signals is easy where I work.
