Module Delivered in
Short Title:  Power Engineering 

Full Title:  Power Engineering 

Description:  This module forms an introduction to electrical power systems and typical components
found in such systems. The module deals with a broad range of theory and analysis relating
to energy distribution, circuit and electromagnetic theory, behaviour of circuits under
differing loading conditions, implementation of power factor correction and the use of
electrical drives. 

Learning Outcomes: 

On successful completion of this module the learner will be able to   Describe methods of generation, transmission, distribution
and utilisation of electrical power.
 Explain the basic operation of major components in
electrical power distribution.
 Describe how RLC series and parallel single phase loads
behave with AC power.
 Describe how balanced 3 phase Star and Delta loads
behave with AC power.
 Explain Active, Reactive and Apparent power and the
method of power factor correction in electrical power
transmission.
 Describe the basic construction and operation of 3 phase
and single phase Induction Motors, synchronous speed,
frequency and torque.
