Overview

Switchgear (and circuit breakers) and transformers are critical components in electrical distribution systems and their operation significantly affects the overall performance of the system. This course will discuss the application, installation, maintenance and testing issues relating to medium and high voltage switchgear, circuit breakers and transformers. Low voltage switchgear will also be covered and you will receive a thorough grounding in switchgear theory and standards. You will gain a solid understanding of the issues associated with the proper application, installation and maintenance of these critical items of equipment with an overriding emphasis on safety. The emphasis is on medium voltage (referred today as high voltage) switchgear which represents most of the switchgear installed on electrical distribution systems. The focus is on air blast, oil, SF6 and vacuum circuit breakers.

Case studies covering the main manufacturers' equipment will illustrate the important practical principles. Other power system protection components will be discussed as well to ensure that switchgear is understood in the correct context. Installation of high voltage distribution and transmission equipment has increased significantly over the years due to ongoing global demand for power. As a result, the need to ensure reliability of operation of power systems is paramount. Power transformers are among the most important and most expensive components of power systems. Their failure can impose extraordinarily high costs on plants, factories and utilities of all descriptions. It is critical that all personnel operating and working with such equipment have a sound knowledge of their operational requirements and maintenance.

This practical course provides knowledge on both the theory and operation of power transformers. The course will develop and enhance an understanding of what is involved in the maintenance of these essential components of the power systems, through the tips and tricks learnt and developed by some of the world's pre-eminent electrical engineers.

How Does it Work?

EIT eLearning courses involve a combination of live, interactive sessions over the Internet with a professional instructor, set readings, and assignments. The courses include simulation software and remote laboratory applications to let you put theory to practice, and provide you with constant support from a dedicated Course Coordinator.


Practical Exercises and Remote Laboratories

As part of the groundbreaking new way of teaching, our online engineering courses use a series of remote laboratories (labs) and simulation software, to facilitate your learning and to test the knowledge you gain during your course. These involve complete working labs set up at various locations of the world into which you will be able to log to and proceed through the various practical sessions.

These will be supplemented by simulation software, running either remotely or on your computer, to ensure you gain the requisite hands-on experience. No one can learn much solely from lectures, the labs and simulation software are designed to increase the absorption of the materials and to give you a practical orientation of the learning experience. All this will give you a solid, practical exposure to the key principles covered and will ensure that you obtain maximum benefit from your course.
