Question 1
In a ACSR conductor why is grease put between steel and aluminium conductors?
Question 2
Statement (i): The expression for the value of inductance L per conductor of an asymmetrically spaced 3-phase overhead transmission line contains an imaginary term.
Statement (ii): The presence of the imaginary term is due to the mutual inductance between the phase conductors and can be eliminated by symmetrically transposing the three line-conductors along the length of the line.
