Course Overview

This Electrical Substation and Switchyard Design course focus on elementary safety standards and practices in substations and switchyard design. An electrical substation is the component of a power system with which voltages are transformed for the transmission, distribution, transformation and switching of power.

A switchyard is a substation that operates at a single level of voltage without transformers. Therefore, the design and understanding of these components play a huge role in most power systems today. This program covers the key elements of these components along with the electrical, chemical, and personal threats that exist in environments that contain substations and switchyards.

Why are the ‘Fundamentals of Electrical Substation and Switchyard Design, Safety and Maintenance’ course at Zoe the best option for you? At the end of this course, you will be able to effectively comprehend the basics of electrical substations and switchyards. The general practices towards handling situations with impending dangers and accidents are also discussed in this course, thereby making its participants more cautious and alert.

This Zoe training course will also provide you with a mastery in the fundamentals of electrical substations and switchyard design. You will also be acquainted with the theories in protective relays, trip schematics and wiring diagrams, auxiliary gear, as well as substation mechanisation and its integration with the overall systems that it is a vital part of.
