How often should relay protection be replaced
Periodic maintenance intervals for protection relays can vary depending on the application and the manufacturer's recommendations. Based on the electrical and mechanical durability of relays, select a relay that meets your equipment, load, and. Mechanical relays, when properly maintained and tested, can last for decades. They are often easy to maintain and repair because replacement parts are still widely available. For this reason, it's not uncommon to find mechanical relays in substations that have been in service well beyond their. Recognising when a relay requires replacement is essential to maintaining the efficiency and safety of automation systems. One of the most apparent signs is unusual noises, such as clicking or buzzing, which may indicate that the relay is struggling to operate correctly.
