Description : Why are overhead transmission lines not insulated?

Answer : Insulators are useful to help separate electrical conductors when they come into physical contact. Overhead Transmission Lines Are Not Insulated: The overhead transmission line is carrying extreme high voltage and ... a whole lot of thick insulation to absorb the heat produced by such high voltage.

Description : Bundled conductors are mainly used in high voltage overhead transmission lines to (a) Reduce line loss (c) Reduce corona (b) Reduce harmonics (d) Increase strength

Answer : Bundled conductors are mainly used in high voltage overhead transmission lines to Reduce corona 

Description : Shunt Inductors are primarily installed in transmission lines to : (A) Improve Power Factor (B) Improve Stability (C) Reduce Ferranti Effect (D) Improve Voltage Profile

Description : Transmission lines are transposed to : (A) Reduce copper loss (B) Reduce skin effect (C) Prevent interference with neighbouring telephone lines (D) Prevent short-circuit between any two lines

Answer : a

Description : Hollow conductors are used in the transmission lines to:  (1) Improve heat dissipation (2) Reduce corona loss (3) Reduce skin effect (4) Reduce the line inductance

Answer : Hollow conductors are used in the transmission lines to: Reduce corona loss.
