Service life of relay protection products
Mechanical relays, when properly maintained, can last for decades, while microprocessor relays provide advanced features but may age over time, especially in their electronic components like electrolytic capacitors. 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. The main purpose of protection and control relay is to protect both human lives and equipment as well as ensure uninterrupted power supply. Industry Leading Life Cycle Policy ABB's products are designed for continuous evolution. It is ABB's goal to protect our customers' investment beyond the. As the durability (life) of the product varies greatly depending on the operating conditions and environment, the recommended maintenance and replacement timings are not specified. The service life prediction structure of relay.
