Protective Relaying Principles & Applications
The rapid growth of next generation power systems creates a real need for updates to protective relay systems to ensure enhanced security, dependability and effectiveness. Engage in comprehensive discussions and analysis about enhanced features of next generation protective relay systems that adapt to changing conditions. This course describes changes that will be implemented as the next generation power system is established.
Learn to apply microprocessor-based relays to detect voltage collapse. Utilize voting logic to minimize misoperations and explore applications that minimize neighborhood blackouts.
This course can be applied to the Electrical Engineering Certificate.
