Question 3

Bundled conductor in transmission lines will not reduces:

Question 4

The disadvantages of HVDC transmission are:

1. It requires costly terminal equipment’s.

2. Converters require considerable reactive power.

3. Harmonic are generated which require filter.

Question 5

An 800 kV transmission line is working under no load condition. The ABCD parameters are A= 0.95∠0° = D, B = 120∠90° Ω/phase, C = 0.5 x 10^-6 Ω/phase. The shunt reactor required to compensate the Ferranti effect at receiving end is
