Course Description
The aim of this course is to provide in-depth knowledge of the major electrical protection principles, applications and schemes associated with generators. The principles and criteria learned here are applicable to both large and small machines.
The proper application of protective relaying requires knowledge of the operating range of each component and an understanding of the interactions of the generating unit and the power system. This is crucial if you are working in power system industry.
Included in the course are generator differential protection, restricted earth fault protection, negative sequence or unbalance protection, protection against inadvertent energization, overcurrent protection, and so on.
