Hi friends,


I am using ADE7763.

as far as now i am finished with Volt, Current, KWh, KVAh ,Frequency and instantaneous KVA (i.e. V * I)


my question is.


how do i find instantaneous Active Power i.e. KW and PF.


according to power triangle.

i thought PF can be calculated as


PF = KWH / KVAH by considering LINECYC register.

but it seems to be not right.


can any one suggest me. how to compute KW and PF.
