In a delta wired system, the line voltage is equal to the phase voltage because they are in what configuration?

In a delta wired system, the line voltage is equal to the phase voltage due to the way the windings are interconnected. In this configuration, each phase winding is connected end-to-end, forming a closed loop, which allows each phase to have the same voltage as the line. This connection creates a path where the phase currents can circulate, leading to the equality of line and phase voltage.

Understanding the delta configuration is essential: it consists of three phases connected in a loop, and each line connects to a phase at the junction of two windings. Since the line connects directly to these junctions, the voltage across each line is equal to the voltage across the corresponding phase. Thus, in a delta configuration, the phase voltage and the line voltage are indeed equal.

This direct relationship is unique to the delta configuration and distinguishes it from other wiring configurations, such as wye (star) systems, where line voltage is greater than phase voltage. This is key in understanding how delta systems operate in electrical networks.
