ADE7953 single phase three wire for 4CT


       Customer use ADE7953 single phase three wire. To use CT induced current through below circuits input to IA channel of ADE7953. Power source is 220Vac and get total power to meet 0.5 class.

      Due to customer request Line A and Line B current needs accuracy (<0.1A). So it add another CT to measure individual current and angle value. If use below 4CT design for actual testing, it is indeed to meet 0.5 class. But is it indeed ok for below 4CT design and connection? Has any problem for it? 

      It is a little urgent and look forward to receive reply. Thank you.
