Power system protection and switchgear plays a crucial role in establishing reliable electrical power systems. Improperly designed protection systems can lead to major power failures. Due to the increasing dependency of electricity, such power failures can have a serious impact on society and the economy. Application knowledge of power system-protection is key when it comes to optimizing the reliability level of electrical infrastructure. With the advances in protection and communication technology in recent decades plus the strong increase of renewable energy sources, the design and operation of power system protection systems has become ever more challenging. The course provides an up-to-date presentation of the role of protective relays in protecting the power system equipment. It provides a theoretical summary along with examples of real-life engineering applications to a variety of technical problems, thereby bridging the gap between the theoretical advances, experimental validations, and practical engineering.

This module offers overview of the protection schemes and evolution of Protective relays.

It's a great course. There are just some minor errors in some lesson's content. In some lessons the professor is saying something but the content shown doesn't match.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
