Purpose of the Electrical Technology Power Systems ATP
Electrical Technology Power Systems trains learners to understand electrical generation, distribution, motor control, transformer operation, fault finding, and industrial automation. The ATP provides a structured path across four terms and ensures that learners gain theory knowledge, practical skills, and exposure to real electrical systems. Teachers must follow the sequence exactly, complete required PAT components, and assess learners according to the School Based Assessment guidelines.
The Electrical Technology: Power Systems Grade 12 Annual Teaching Plan (ATP) for 2026 is structured across four terms, focusing on electrical generation, transmission, motor control, and programmable logic controllers (PLCs), culminating in the final National Senior Certificate (NSC) examinations. This guide is based on the 2023/24 ATP framework.
