ECTS Credits:4
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
  1. Describe methods of generation, transmission, distribution and utilisation of electrical power.
  2. Explain the basic operation of major components in electrical power distribution.
  3. Describe how RLC series and parallel single phase loads behave with AC power.
  4. Describe how balanced 3 phase Star and Delta loads behave with AC power.
  5. Explain Active, Reactive and Apparent power and the method of power factor correction in electrical power transmission.
  6. Describe the basic construction and operation of 3 phase and single phase Induction Motors, synchronous speed, frequency and torque.
