The Useful Life of Microprocessor-Based Relays: A Data-Driven Approach

Join us for a recorded technical presentation where SEL presenters Derrick Haas and Karl Zimmerman will discuss the useful life of microprocessor-based relays. Confidence in microprocessor-based protective relays has steadily increased over the four decades since their invention. As the service life of these devices exceeds multiple decades, questions regarding when and how to strategically replace the relays are increasing.

During the webinar, you will:

• Learn definitions of terms associated with reliability of protective relays.
• See actual field-observed life cycle reliability data.
• Learn about replacement strategies.

Learn how reliability data can be your compass as you navigate how to manage an aging fleet of microprocessor-based relays.
