Star Connected 3 Phase Supplies

What is the relationship between the line voltage (VL) and the phase voltage (VP) in a star connected load?

• VL is equal to VP

• VL is greater than VP

• VL is less than VP

• VL is the square root of three times VP

In a star connection, how does the line current compare to the phase current?

• The line current is the same as the phase current

• There is no relationship between the line current and the phase current

• The line current is less than the phase current

• The line current is greater than the phase current

What is a main advantage of the star connected system?

• It requires less wiring

• It allows us to have two voltages

• It is only suitable for balanced loads

• It allows for only one voltage

Why do we tend to use a star connection when we have an unbalanced load?

• Because it allows for a single phase connection

• Because it is more cost-effective

• Because it simplifies the wiring

• Because each of the three loops is connected to the star point

How is the line voltage related to the phase voltage in a star connection?

• The line voltage is equal to the phase voltage

• The line voltage is less than the phase voltage

• The line voltage is the square root of three times the phase voltage

• The line voltage is twice the phase voltage
