ADE7878 AC Input is Delta ( How to Measure phase B Voltage ? )

Category: Hardware
Hello

I Want to use ADE7878, AC input power supply is DELTA configuration. (Before using AD7953 WYE power supply input VAP to L1, VBP to L2, VCP to L3, VN to neutral, you can measure the voltage of L1, L2, L3)

1. Use Phase B as a common ground according to the figure below, so that the voltage of Phase B cannot be measured?
