THESE QUESTONS ARE FROM THE SUBJECT POWER SYSTEM FUNDAMENTALS AND FROM THE TOPIC ELECTRICAL DESIGN OF OVER HEAD TRANSMISSION LINES AND MAKE SURE THAT YOUR ANSWER IS CORRECT

Problem-1

A single phase transmission line has two parallel conductors 1·5 meters 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 at the corners of an equilateral triangle of 2·5 m side. The radius of each conductor is 1 cm. Calculate : (i) line to neutral capacitance of the line, (ii) charging current per phase if the line is maintained 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 loop inductance per km of the line

The synchronous generator or alternator is an electrical machine that converts the mechanical power from a prime mover into an AC electrical power at a particular voltage and frequency. The synchronous motor always runs at a constant speed called synchronous speed. A three phase, 8 pole, synchronous Generator is coupled to a diesel engine running at 500 rpm. It supplies an induction motor which has a full load speed of 1440 rpm. Find the percentage slip and number of poles...

Electrical power is to be produced from a steam turbine connected to a nuclear reactor. Steam is obtained from the ractor at 540 K and 36 bar, the turbine exit pressure is 1.0 bar, and the turbine is adiabatic. a) Compute the maximum work per kilogram of steam that can be obtained from the turbine. A clever chemical engineer has suggested that the single-stage turbine considered here be replaced by a two-stage adiabatic turbine, and that the steam exiting from...
