i wanna ask about the availability of current transformer and voltage transformer in the market as i need it in low voltage assembly i.e 25 volts ac. actually i need to make power factor meter which require a current transformer and a voltage transformer, each of which gives waveform out of which zero crossing point will be extracted using op-amp and then ultimately using microcontroller calculate the power factor. Is this the good concept if not then would u suggest some other method plxxxx.
