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-4
Find the inductance per km per phase of a 3-phase overhead transmission line using 2 cm diameter conductor when these are placed at the corners of an equilateral triangle of side 4 meters.
Problem-5
The three conductors of 3-phase overhead line are arranged in a horizontal plane with a spacing of 4 m between adjacent conductors. The diameter of each conductor is 2 cm. Determine the inductance per km per phase of the line assuming that the lines are transposed.

ASSIGNMENT: A CRITIQUE OF THE DELIVERY OF HOLISTIC
SUSTAINABILITY IN ELECTRICAL SYSTEM DESIGN
PLEASE note a key phrase in the brief is: It is important that
the student takes the perspective of their prospective profession
in this assignment. They should consider to what extent their
chosen profession can or cannot influence the delivery of holistic
sustainable solutions. Some aspects may be beyond the profession’s
control, others within its sphere of influence. The barriers to
delivery of holistic sustainability solution in...

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...
