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.

 

Regards,

Umesh
