Delta Connected 3 Phase Supplies

Why is a Delta connection used in a three-phase load?

• To reduce the number of wires needed for power transmission

• When there's an unbalanced load

• To increase the complexity of the connection

• To increase the need for a neutral connection

What does VL represent in a Delta connected three-phase load?

• Phase voltage

• Line voltage

• Line current

• Phase current

What is the relationship between line current and phase current in a Delta connected three-phase load?

• Line current is equal to phase current

• Line current is less than phase current

• Line current is the square root of 3 multiplied by the phase current

• There is no relationship

In a Delta connected three-phase load, how is the line voltage compared to the phase voltage?

• Line voltage is higher

• Line voltage is lower

• Line voltage and phase voltage are the same

• Line voltage is twice the phase voltage

What is the purpose of using only three wires in a Delta connection for power transmission?

• To simplify the wiring system

• To increase power efficiency

• Because there's no need for a neutral connection

• To connect multiple three-phase motors together
