Question

e) correct? (circle all t A. B. C. D. E. F. The current must not produce heat in the transmission lines The transmissions lines only carry active power from one place to another. It is important to keep the reactive power minimum on transmission lines. The voltage drops over the transmission lines is not a concern. Keep the line losses small is the key issue for high transmission efficiency. Inductors and capacitors can be used to reduce the losses on transmission lines.

Answer 1

!. The current must not produce heat in transmission line.(Thats why step up transformer is used to reduce currrent by stepping up voltage.) True

2.Transmission line only carry active power from on place tro another. False

3.It is important to keep reactive power minimum on transmission line.(To maintain voltage level and to improve stability of system by reducing reactive power and increasing active power.)True

4.The voltage drop across the transmission line is not the concern.(for efficient operation voltage drop is important) False

5.Keep the losses small is the key of high transmission efficiency.True

6.Inductors and capacitors can be used to reduce losses on transmission lines.(inductor absorbs reactive power and capacitor generate reactive power.)True
