 Synchronous impedance curve

The synchronous impedance curve is a graphical representation used in electrical engineering, particularly in the analysis of synchronous machines such as synchronous generators and synchronous motors. It illustrates the relationship between the voltage, current, and power factor of the machine under synchronous operation conditions. ### Key Elements: 1. **Synchronous Impedance**: It is defined as the total impedance of a synchronous machine when it is operating under synchronous speed, which includes both the resistive and reactive components.
