I need to measure the peak value of the mains voltage, and I'm gonna use a peak detector. A simple diode, plus an RC in parallel with a suitable time constant. But there seems to be a problem: voltage surges, a high voltage pulse that can charge the cap to an incorrect peak and make my peak detector useless.
My question is: how much are these surges important, and is it possible to filter these surges effectively?
