SYNOPSIS:


Engineering  professionals  need  a working  knowledge  of  electrical
components,   instruments,  machines  and  safety   devices   commonly
encountered  in the engineering workplace. To provide that  knowledge,
this   unit   introduces  the  principles  of  materials,  components,
instruments and machines for electrical energy conversion. Analysis of
dc  and  ac  circuits,  as  well as test  measurements  on  resistors,
capacitors, inductors, transformers, motors, generators, batteries and
rectifiers, form part of the practical work.

OBJECTIVES:

A student who has mastered this unit should be able to :

  1. state the electric, magnetic, thermal and chemical effects in
    common electrical devices and make simple calculations using
    the basic laws and conventions for energy conversion;
  2. describe common electrical components, devices and signal
    sources and their principles of operation in simple dc and ac
    circuits;
  3. use electrical instruments and cathode ray oscilloscope for
    the measurement of voltage, current, resistance, energy, power
    and power factor;
  4. state and apply Laws and Theorems to analyse dc and ac
    circuits, eg ammeter shunts, voltmeter multipliers, voltage
    dividers, bridges, battery connections, cable voltage drop and
    generators in parallel;
  5. construct phasor diagrams and use phasors to analyse single
    phase and three phase circuit measurements relating to lamps,
    capacitors, transformers, motors and generators;
  6. conduct tests to determine the no load and on load operation
    of transformers, motors and generators;
  7. state the applications of transformers, auto transformers and
    instrument transformers;
  8. explain the principles of operation and the applications of dc
    and ac motors and generators;
  9. draw and explain the circuit diagrams for transformer, dc
    motor, ac generator and induction motor;
  10. state the principle of rectifiers, inverters and battery
    chargers and their applications;
  11. explain the need for earthing, safety fuses, circuit breakers,
    earth leakage circuit breakers and lightning protection;
  12. describe with line diagrams, typical electricity supply
    systems.

OTHER REQUIREMENTS:

1    Residential  school attendance is compulsory,  and  a  report  of
     these  sessions,  deemed satisfactory by the  examiner,  must  be
     submitted by the due date to obtain a pass grade.
2    The  final  examination consists of two sections - a closed  book
     multichoice  answer part and an open book, problem solving  part.
     The  closed book part is worth approximately 35% of the marks for
     that assessment.
3    To  be  eligible for a mark for Assignments 1 and 2 (CML S1B  and
     S2B),  a  prior attempt should have been submitted for CML  Tests
     F1A or F1B or F1C and F2A or F2B or F2C.
4    To  be  eligible for a mark for Assignments 3 and 4 (CML S3B  and
     S4B),  a  prior attempt should have been submitted for CML  Tests
     F3A or F3B or F3C and F4A or F4B or F4C.
5    To  gain  a C grade, in addition to a total mark of approximately
     50%,   satisfactory   performance  will  be   required   in   the
     assignments,  laboratory work report, and the final  examination.
     The  standard for satisfactory performance is at least 50% of the
     available marks for that assessment.
6    To  gain a B grade, in addition to meeting requirement 3, a total
     mark  of approximately 65% will be required. To gain an A  grade,
     in   addition  to  meeting  requirement  3,  a  total   mark   of
     approximately  75%  will be required. To  gain  a  HD  grade,  in
     addition  to meeting requirement 3, a total mark of approximately
     85% will be required.
7    The penalty for late submission of any assessment is normally the
     loss of all marks for that assessment.
8    The   Faculty  of  Engineering  and  Surveying  will  NOT  accept
     submission  of  hand written or typed assignments  by  facsimile,
     email  or computer diskette. Students in remote locations who  do
     not  have regular access to postal services may be given  special
     consideration.
9    A  minimum  standard of communication skills must be demonstrated
     in order for a passing grade to be achieved.
