Protection Advancements to Benefit Generators of All Sizes and Types

A comprehensive solution for generator, generator bus, and generator step-up transformer protection can be seemingly complex at a generation plant but is nonetheless necessary to protect facility investments. However, all of this is now possible with just one relay—the new SEL-400G Advanced Generation Protection System. It can be applied to protect generators of all sizes and types, including hydro, pumped-storage hydro, steam turbine, and combustion gas turbine generators.

During this webinar, you will learn how to:

• Protect generators and generator step-up transformers with two independent universal differential zones.
• Provide protection during generator startup using two independent frequency zones with wide-range frequency tracking.
• Increase machine life with advanced generator monitoring capabilities.
• Reduce complexity for pumped-storage generation using internal relay logic that eliminates the need for external switching.
• Implement comprehensive protection schemes, such as loss-of-field protection, for generator and auxiliary systems.
