ADE775X Wiring for 3-wire Delta

Hi,

I'm using ADE7758 & ADE7878 in my products.

All our system are in 4-wire Wye mode.

 

We try to connect the unit in 3-wire Delta mode but we have problem with the meassurments.

 

The problem is with the PF for each phase (1 & 2 , 3 in always zero in this mode).

 

Assume that every 1 second I read the energy registers (P & Q & S)

Is the total PF for the unit is equal to Total Active Energy (P)  divide by Total Apparent energy (S) (P/S)?

 

Regards,

Doron
