Power Systems - Solving our Electricity Problems Today

Electrical systems refer to applications of electricity where heavy current from mains supply is used in a number of applications. In Grade 10, the learner is introduced to direct current (DC) and domestic installations. The circuitry as it is found in a typical South African home, in accordance with the requirements of the SANS 10142, forms a major part of the learner’s curriculum. 

In Grade 11 the learner is introduced to light industrial single phase applications where motors and transformers are  used. Programmable Logic Controllers (PLC) is introduced in Grade 11, and is continued in Grade 12. 

The main focus of the Grade 12 year in Electrical Technology contextualises the generation, distribution and application of  three phase power in motors and transformers as well as control using PLC. By the completion of Electrical specialisation in Electrical Technology, a learner will have knowledge of electrical heavy current in single and three phases from the supplier to the consumer, with domestic, light and heavy industrial motor and control. 

A learner in Electrical Technology may opt to become an electrician and work in the manufacturing industry with specific  focus on maintenance and repair of electrical installations and machinery. Further studies for such a learner will typically be along the lines of an FET college in conjunction with an internship at a local industry. Further studies could be pursued through a university for learners with the required subject combinations.

Through the integrated completion of theoretical work, practical assessment tasks (PAT) and simulations, the following  skills are developed:
