T&D MODULE 2

A transmission line can be represented as

• a circuit which contains R &L in series and G&C in shunt

• a circuit which contains G in series and L&C in shunt

• a circuit which contains R&C in series and G&L in shunt

• none of the above

unsymmetrical spacing configurations,unsymmetrical spacing causes the voltage induction in the communication line cause the line interface

The above problem cab be eliminated by

• Transposition

• Three phase line

• parallel lines

• line outage

The value of inductance per conductor in a three -phase line is____________ time(s) the loop inductance for the single phase lines.

• 2

• 1/2

• 1

• 1/3

the fictitious resistance "r" implemented in the conductors for the calculation of inductance is

• 2R

• 0.7788R

• R/0.7788

• 1/R

capacitance between two conductors of a line is 6F.capacitance of each conductor to neutral will be

• 2F

• 12F

• 4F

• 8F
