I've measured the phase voltage Va,Vb,Vc
But I want to measure the line voltage VAB=??????? (ADE7758)
Please Help me
The figure below shows the 3 wire 3 phase delta configuration:
If you connect the meter in this configuration, you can measure voltage difference between VAP and VN to be VAB. Phase B is taken as the reference here.
But , in simpler terms, you can measure VAB = VA - VB in the wye configuration that you have right now.
Are you connecting the chip in 3 phase 3 wire delta configuration? If you do so, you can select phase B as the reference and thus measure Vab and Vcb from the chip directly.
If this is not your configuration, please let me know the purpose of this measurement and your application, so that I could help you out better.
What is three phase delta configuration? Please explainI've attached the data sheet of the three-phase
Similar to Figure 4 on page 5 of Evaluation Board Documentation ADE7758 Energy metering IC
I use the registry to determine the line voltage?
