Question

By using bundle conductor ______

• A. The self GMD is decreased, the inductance is reduced, the surge impedance is reduced
• B. The self GMD is increased, the inductance is reduced, the surge impedance is reduced
• C. The self GMD is increased, the inductance is increased, the surge impedance is reduced
• D. The self GMD is increased, the inductance is reduced, the surge impedance is increased

Hint:

Using bundled conductors helps control corona effects and improves line efficiency by reducing impedance.

Answer 1

The Correct Option is B

Bundle conductors increase the self-GMD (Geometric Mean Distance), which in turn decreases the inductance and the surge impedance of the transmission line. This improves power transmission capability and reduces corona loss.
