In a Y-Y source/load configuration, how do the phase current, line current, and load current relate in each phase?

In a Y-Y (Y-connected) configuration, each phase of the load is directly connected to the corresponding phase of the voltage source. In this arrangement, the phase current, line current, and load current all occur in the same manner due to the direct connection of each component.

1. Phase Current: This is the current flowing through each individual load connected across the phases. In a Y-configuration, the load is connected to the line-to-neutral voltage, which results in the phase current being the same as the current flowing through the load.

2. Line Current: This term refers to the current flowing through each line leading to the loads. In a Y-connected system, this line current is the same as the phase current because there is only one path for the current to flow in each phase. Therefore, for each phase, the current from the source directly feeds into the load without any additional paths or transformations.

Since both the phase current and the line current are identical due to this configuration, it follows that the load current, which is also the current through the load in each phase, is equal to both of them as well. Thus, in a Y-Y configuration, the relationship captured is that phase current, line current,
