We use this ADE7878 as our energy metering IC. We measured 3P4W connection and it is good. But we hope to know
1. If we connect this ADE7878 with 3P3W and no neutral line, how to connect it?
2. We want to measure three phase current, but we only want to use one phase voltage (may be line voltage or phase voltage), can we connect 3 inputs (VAP, VBP, VCP) together to an external line and another line connected to VN?
Thanks again and best regards
