Which of the following equation correctly represents the exact phasor ...
Phasor Diagram of Transformer:
Transformer phasor diagram represents the relationship between the primary and secondary voltages and currents in a transformer.
Explanation:
- V1= E1+ I1R1+ jI1X1: This equation correctly represents the phasor diagram of a transformer. Here, V1 is the primary voltage, E1 is the primary induced voltage, I1 is the primary current, R1 is the primary resistance, and X1 is the primary reactance. The equation shows that the primary voltage is the sum of the induced voltage and the voltage drop due to primary resistance and reactance.
- V1: Represents the primary voltage in the phasor diagram.
- E1: Represents the primary induced voltage in the phasor diagram.
- I1R1: Represents the voltage drop due to primary resistance in the phasor diagram.
- jI1X1: Represents the voltage drop due to primary reactance in the phasor diagram.
This equation accurately captures the relationship between the primary voltage, induced voltage, current, resistance, and reactance in a transformer, making it the correct representation of the transformer phasor diagram.
