If the diameter of the conductor is increased then _____________

• inductance increases

• inductance remains unaltered

Transposition of transmission line is done to

• Reduce corona

• Balance line voltage drop

• Reduced skin effect

• Reduce line loss

The term self GMD is used to calculate

• Capacitance

• Inductance

• Resistance

• Both Capacitance and Inductance

If we increase the spacing between the phase conductors, the line capacitance

• increases

• decreases

• remains unaffected

ACSR means

• Aluminium core steel reinforced

• Aluminium conductor steel reinforced

• Aluminium copper steel reinforced

• all conductor steel reinforced

The skin effect can be reduced by using

• Bundled conductors.
