In a 3-phase wye system, the line current is what multiple of the phase current?

In a 3-phase wye (or star) system, the relationship between line current and phase current is crucial for understanding how power is distributed in such systems. In a wye configuration, each phase is connected to a common point (neutral), and the line current is equal to the phase current. This equality occurs because the line current flows directly through each corresponding phase coil.

Thus, for a 3-phase wye system, the line current can be stated as the same magnitude as the phase current, confirming that the line current is indeed 1 times the phase current. This concept is essential for electrical engineers and technicians when calculating power, load distribution, and ensuring that systems are designed to handle the correct amount of current without causing overloads.

Other options suggest differing multipliers for line versus phase current, which do not apply to a wye configuration, further highlighting the accuracy of the understanding that in such a system, the line current equals the phase current.
