THESE QUESTONS ARE FROM THE SUBJECT POWER SYSTEM FUNDAMENTALSAND FROM THE TOPIC ELECTRICAL DESIGN OF OVER HEAD TRANSMISSIONLINES AND MAKE SURE THAT YOUR ANSWER IS CORRECT
Problem-1
A single phase transmission line has two parallel conductors 1·5meters apart, the diameter of each conductor being 0·5 cm.Calculate line to neutral capacitance for a line 80 km long.
Problem-2
A 200 km, 3-phase transmission line has its conductors placed atthe corners of an equilateral triangle of 2·5 m side. The radius ofeach conductor is 1 cm. Calculate : (i) line to neutral capacitanceof the line, (ii) charging current per phase if the line ismaintained at 66 kV, 50 Hz.
Problem-3
A single-phase line has two parallel conductors 1 meter apart.The radius of each conductor is 0·5 cm. Calculate the loopinductance per km of the line
