SUMMARY
This discussion focuses on calculating neutral current in three-phase unbalanced systems, specifically in a 3-phase, 4-wire wye configuration. For balanced loads, the vector diagram is straightforward, while unbalanced loads require a different vector analysis approach. The absence of one phase, such as the C Phase, indicates an unbalanced condition that significantly affects neutral current calculations. Understanding vector analysis is essential for accurately determining these currents in practical applications.
PREREQUISITES- Three-phase power systems
- Vector analysis fundamentals
- Wye and delta configurations
- Neutral current calculations
- Study neutral current calculation methods in unbalanced three-phase systems
- Explore vector analysis techniques for electrical engineering
- Learn about the impact of load imbalance on neutral current
- Investigate simulation tools for three-phase power systems
Electrical engineers, power system analysts, and students studying three-phase systems will benefit from this discussion, particularly those focusing on load balancing and neutral current calculations.

For balanced loading on a 3-phase, 4-wire wye system like this,
the vector diagram would looks like this:
Now follow this Basics of Vector Analysis.
Now for unbalanced loading on a 3-phase, say like this,
the vector diagram would look like this, since there's no C Phase (definitely unbalanced :D):
Now follow this Vector Analysis.
Good Luck
