*Here Vct is considered as the CT secondary voltage signal required to feed the AtoD converter of uC and it is assumed to be less than absolute maximum rating of input pin of AtoD converter. Kindly keep Vct = Vout below 1 Volts for accurate reading this implies that lower value of burden resistance helps increase accuracy. Using higher bit ADC increases the precision level. Kindly select at your discretion.
