Electrical Engineering MCQs on Three Phase Power Systems
In case of a ∆-connected source feeding a Y-connected load
- Each phase voltage equals the corresponding load voltage
- Each phase voltage equals the difference of the corresponding load voltages
- Each phase voltage is 60° Ωut of phase with the corresponding load voltage
- Each phase voltage is one-third the corresponding load voltage
Correct answer: 2. Each phase voltage equals the difference of the corresponding load voltages
