SCQF Level 8


  • Engineering

Why take this course?

This Unit has been developed to provide candidates’ with an opportunity to develop knowledge and understanding about batteries, standby/emergency generators and UPSs (Uninterruptible Power Supplies).

On completion of the Unit the candidate should be able to:

  • Identify operation, characteristics and applications of electrical batteries
  • Outline principal operating features/main performance characteristics of standby/emergency generator sets.
  • Analyse construction, operation and performance characteristics of UPS (Uninterruptible Power Supplies)

What you will experience

Standby, or back-up, systems are very important in Electrical Engineering as they ensure the maintenance of electrical energy when other power systems fail.

In this Unit you will examine three types of back-up systems: namely batteries, generators and UPS (Uninterruptible Power Supplies). Batteries come in many shapes and sizes and different battery types are more suitable for particular applications. In this Unit you will learn about the construction and principles of operation of basic batteries and the characteristics and applications of a range of different battery types.

The subject of standby generators is very large and it would be impossible to teach you all about them in one Unit. In this Unit you will learn about the construction and principle of operation of different types of standby generator, how generators are driven, the key performance characteristics of generators, and other technical requirements relating to generator operation including control, electrical protection, installation, safety and maintenance.

UPS (Uninterruptible Power Supplies) are used widely in industry and commerce. In this Unit you will learn about the basic function of this type of power supply. How they are constructed and operate, what their key performance characteristics are, how to ‘size’ them to supply different types of equipment and how software can be used to control some of their operations.

Assessment for this Unit will comprise of a two hour written test following the delivery of Outcomes 1 to 3.
