This training course is specifically designed to provide participants with a comprehensive understanding of power system protection schemes and devices, including protection relays, fuses, circuit breakers, and other protective equipment. In modern power systems, protection systems play a crucial role in ensuring efficient plant operations, facilitating utility switching, managing industry load transfers, implementing maintenance programs, and guiding investment policies.

Course Objectives:

At the end of this training course, you will learn how to:

Select fit-for-the-purpose protection relays and other related devices
Calculate fault levels and loadings of feeders and branches
Develop and analyze typical power systems and their associated protection systems
Analyze protection logics and coordination between protection devices
Establish communication between protection devices and controllers
