I have an unbalanced star configuration with three different line currents as follows; 5.28A, 2.58A and 4.78A. Is it possible to obtain the neutral current, recorded as 2.4A, from these three values and if so how? If any more readings are required I can provide them.

Cheers

Add them together as complex currents (including the phase angles). Assuming your sources are at 0, 120, and -120, I get 2.48 at an angle of -50.
