In a delta-connected source driving a delta-connected load, what can be said about the load voltage?

In a delta-connected source driving a delta-connected load, the load voltage relates to the line voltage in a specific way due to the properties of delta connections. In this configuration, each load is connected directly across the lines where the line voltage is present, which means the voltage across each load element is equal to the line voltage for that phase.

In a delta connection, the voltage across each load element (phase voltage) is the same as the line voltage that connects them. Since each load in the delta configuration is across two phases of the supply, it receives the full line voltage. Consequently, this results in the load voltage being equivalent to the line voltage for that specific phase, maintaining a direct relationship.

This is fundamental in three-phase systems and illustrates the efficient distribution of voltage and current in such configurations. Thus, understanding the relationship between line and load voltages in delta connections is crucial for correctly analyzing three-phase systems.
