Relay protection expired for 15 years
On average, mechanical relays typically last between 1 to 5 years due to their moving parts, which are prone to wear and tear. In contrast, solid-state relays offer a significantly extended lifespan, often exceeding 15 years. When this happens to the protection relay but the existing protection functionality is still sufficient replacing all relays with new ones of the same type may prove to be the best cho y as no new wiring is. ays has steadily increased over the four decades since their invention. As the service life of these devices exceeds multiple decades, questions rega ding when and how to strategically replace these relays are increasing. This paper defines terms associated with the reliability of protective. This utility standard establishes the requirements for testing and maintaining protection systems, automatic reclosing, and sudden pressure relaying.
