Generator Protection
Course Highlights

This online engineering PDH course presents topics related to generator protection technical implementation. This course was made as a reference guide for generator protection. Protection relays that are described in this course are applicable to one or more generator protection schemes.


There are a number of protection relay types and those are used for protection against a wide variety of conditions. These protection relays protect the generator or prime mover from damage. Also they are used for protection of the external power system or the processes it supplies. The basic principles that are described in this course apply equally to individual relays and to multifunction numeric relays.


This 4 PDH online course is intended for engineers with a desire to understand the fundamentals of generator protection. Upon successful completion engineers will be able to address key generator protection concepts, terms and characteristics.
