I am trying to find out the power consumption for a 3 phase balanced system below:
I only have access to the L1, L2, L3 and N connection points at the main connection box and I only know that it is connected to a mixture of 3 phase and single phase loads.
The RMS voltage measurements between each line and natural is as below:
V(L1 to N) = 241.7V
V(L2 to N) = 242.1V
V(L3 to N) = 244.0V
The voltage measurements between each line is as below:
V(L1 to L3) = 420.9V
V(L1 to L2) = 418.7V
V(L2 to L3) = 421.7V
The current measurements were taken using clamp meter and values are as below:
I(L1) = 9.99A
I(L2) = 10.34A
I(L3) = 10.05A
I(N) = 0.45A
Without knowing if the load is Y or Delta, how can I compute the power consumption in this setup?
