Hi There
The question I have is the following
If you have a 4 wire 3 phase system and Ia=20A@.8pf, Ib=5A@.6pf and Ic=0A because of a blown fuse. What is the Neutral current.
I have found that in an unbalanced system In=Ia+Ib=Ic so knowing this I worked out what In would be for example.
In=16+j12+3+j4+0
In=19+j16
In=24.8@40deg (polar)
I have the answer which is 16.75@-48.7deg but am unsure how the book come up with this. Am i using an incorrect formula?
Does anyone know of any good electrical engineering books with examples that have been solved and worked though step by step?
Thanks
