In a 3-phase, 4-wire system with a voltage of 0.38/0.22 kV and eight loads of 2 kVA each, the current in the neutral line can be calculated based on the load distribution. With three loads on phases A and B and two loads on phase C, the asymmetry leads to a neutral current. The neutral current is approximately 10 A, derived from dividing the total load of 2 kVA by the phase voltage of 0.22 kV. This calculation accounts for the vector nature of the loads, ensuring that the neutral carries the imbalance. Understanding these principles is crucial for effective electrical system design and load management.
