Select the INCORRECT statement with regards to a three-phase star-connected AC circuit.
The phase voltage is higher than the line voltage.
The question asks to identify the incorrect statement about a three-phase star-connected AC circuit. Let's analyze each statement:
The line voltage is the voltage between any two lines of the circuit. This statement is correct. Line voltage is the voltage measured between any two of the three lines in a three-phase system.
The phase voltage is the voltage between the neutral point and any phase of the circuit. This statement is also correct. Phase voltage refers to the voltage between one phase and the neutral point in a star connection.
The line voltage is higher than the phase voltage. This statement is correct. In a star connection, the line voltage is \( \sqrt{3} \) times the phase voltage. Therefore, \(V_{line} = \sqrt{3} V_{phase}\).
The phase voltage is higher than the line voltage. This statement is incorrect. As explained above, the line voltage is always greater than the phase voltage in a star connection. This makes this statement the incorrect one.
Therefore, the incorrect statement is that the phase voltage is higher than the line voltage.
