Description

Electrical equipment maintenance and testing is one of the most important aspects of the substation system. Without protection, any system could fail. So it is imperative that safety and protection be given utmost importance to avoid catastrophes. For fault locating to be efficient and accurate technical staff must have expert knowledge to keep employees safe while working on or around high voltage power generation, transmission and distribution systems and equipment.
This course is designed to help students to understand the substation design and safety procedures to provide a safe environment for substation personnel.
