Modern Power System Protection: Applications and Performance Analysis Course
Introduction:
Protection systems are installed to prevent faults from damaging the electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system. Recent changes in technology together with changes in the manner in which Utilities and Industrial organizations operate has greatly emphasized the development of integrated protection and control.
Course Objectives:
By the end of the training, participants will be able to:
- The nature of different types of electrical faults and the effect these faults can have on company assets
- Understanding of electrical fault protection systems
- Practical solutions for specifying and operating protection systems
- Comprehensive understanding of principles and selection of protection relays and protection schemes
- The requirement for testing of relays and protection systems
Who Should Attend?
This course is intended for all Engineers and Senior Technicians from Electrical Utilization Companies and Industrial organizations, Building and Services Professionals, who have to deal with the aspects of electrical and industrial power systems protection, control and operation will also find the course beneficial. Participants need no specific requirements other than a good understanding of electrotechnology and some relevant experience.
