In a delta system, which two voltages are equivalent?

• A. Line voltage and line current
• B. Phase voltage and phase current
• C. Line voltage and phase voltage
• D. Line current and phase current

Answer: (C)

In a delta system, the relationship between line voltages and phase voltages is crucial for understanding the system's operation. In this configuration, the line voltage—measured between any two phases—equals the phase voltage—the voltage across each individual winding—since the phases are connected in a triangular configuration. This equivalence means that the voltage across each component in the system is the same when measured at the line level. This contrasts with other elements, such as currents—where line currents differ from phase currents due to the nature of how they split and combine within the delta setup. Understanding this relationship is essential for proper calculations in power systems, as it helps in determining how voltage and current are distributed across the different phases.
