Synopsis

Herein the learner shall follow electrical power on an exciting journey from its source at the electrical power generating station, along the high voltage transmission lines on the tall steel towers that span the countryside, to the various substations along the way and then through distribution lines along the roadways to its ultimate destination where it is fed to industrial consumers and domestic customers.

We will make frequent stops on our journey to discuss the devices and technologies at strategic points so as to gain meaningful insight into the workings of this lifeline of modern civilization. Our current existence is so dependent on electricity that we can become much disoriented without it. Just think of waking up tomorrow with all electricity set to zero. Indeed, wakeup you may not, since an electrical signal is needed for you to so do.

Essentially your work covers electrical plant and machinery. Much effort is spent on the ubiquitous transformer - an indispensable electromagnetic interlink device . You will understand the basics of power transformers, autotransformers, CTs and PTs. At the generating end you will meet three phase synchronous ac generators and stepup transformers. At the substations you learn about relays, circuit breakers and protection mechanisms. You also learn why Tesla's AC system is superior to Edison's DC system for electrical power.

At the distribution end your studies involve utility pole step down transformers and earthing methods together with the main features and characteristics of ac and dc motors including ac motor starter circuits and dc motor speed control techniques. You will also learn about the significance of power factor and the need to optimize it. Electrical measurements and metering techniques within the electrical power system are included as a necessary part of your training.

Synopsis

This unit has been designed to enable a learner to explore the principles and applications of electronic devices and circuits. Electronic circuits process electrical signals in consumer appliances and in instrumentation and control systems.

Passive devices (R,L, and C) and active devices (Diodes, Transistors, and ICs) are engaged in specific designs to form functional electronic circuits. These circuits are the basic building blocks of electronic systems and can be interconnected in diverse ways to form useful systems. These systems are integrated into the ever-increasing population of  intelligent signal processing machines which underpin our digital civilization.

You will visit both the analog and digital worlds to learn about devices, circuits, signals and systems. Prerequisites are a good knowledge of mathematics and physics coupled with a curiosity to explore ideas, to perform experiments and to build systems.

The course content includes BTEC HND Level 4 material and involves first year University work. This means that you need to manage your time wisely to ensure that you may properly address the needs of the course. If done correctly, you can maximize your benefits and be able to achieve the success you desire.

Thank You.
