davidbeach,
Data is not the problem, I get from my power monitoring board more then enough data.
let's go to the basic:
I get voltage and current for each phase:
I1=47.8A I2=59.1A I3=69.7A
V1=244.4V V2=247.3V V3=245.9V
PF=~1
What is the Power for Delta connection?
My board gives a power...
Hi,
now I'm confused, Delta connection doesn't have N leg, so how come we still have the V(LN) we should only have V(LL)..?
davidbeach, what is the correct answer?
so given the current for each phase, which voltage should we used to calculate the power? and if the total power in the sum of...
Yes I have used the correct formula.
For each phase:
Pph=(Aph*Vph(LN)*PF*3)/1000
Pph1=32.77kw Pph2=36.42kw Pph3=36.83kw
the Power monitoring board gives P=38.6kw
So avereging the phases is more like it, is it correct?
Thanks,
Gadol
Thank you so much, it is very helpful info.
When I add the 3 calculated power for each phase I get unrealistic value of total power, but when I avgerage the 3 power values per phase it's matchs my device power rating?
Do I do the right calculation by averaging the power for each phase?
Thanks...
Bill, Alan thank you so much for replaying.
The data that I get from my monitoring board are: A, V(LL), KVA,PF and KW with accumaltive Kwhr. the reason for my question is that my calculated power,
the sum of (A*V(LL)*PF*3)/1000 per phase does not match the KW from my board.
In addition can I...
