# How to calculate neutral current

 When balance load 3 phase system neutral current zero.  Unbalanced load, three phase  - how to calculate Natural Current ? Is there any formula or other method? asked 11/20/2013 siva2

 Sum of complex values through L1, L2 & L3 phases shall give u the complex value of current through neutral conductor. If u wanna calculate RMS value, you have to calculate from complex value for neutral current as: sqrt(Re(In)^2+Im(In)^2) this number u have to divide with sqrt(2) and that is RMS value of neutral current. answered 12/19/2013 Mirko Lezajic 8
