Generator Protection

Generator Protection

Author: Velimir Lackovic

Protection relays are used as part of generator protection schemes, and they are available in various configurations that allow them to be used under a variety of conditions. These protection relays protect the generator or prime mover from damage, and they also provide protection for the external power system and the processes it supplies. The basic principles that are described in this course apply equally to individual relays and to multi-function numeric relays. The protection engineer must balance the cost of using a particular relay with the consequences of generator damage. The complete loss of a generator may not be catastrophic if it represents a small part of the overall investment in an installation. However, the impact on service reliability and upset to loads must also be taken into consideration because the damage or loss of product in a continuous processes can be substantial. The challenge for design engineers is that every generator protection solution is unique to the specifics of the application.

This course is appropriate for engineers interested in learning the fundamentals of generator protection. It covers issues related to generator protection and the technical implementation of those solutions. Upon successful completion engineers will be able to address key generator protection concepts, terms and characteristics.

Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty (20) questions to earn 4 PDH credits.
