Asset Management Plan Protection Relays
Protection relays are designed to trip circuit breakers in response to network faults or abnormal network conditions to prevent or minimise damage to plant and equipment, and play a significant role in

Home / Is relay protection an obsolete product
Most relays installed in the 1990s and early 2000s have reached their end-of-life with manufacturers announcing they will no longer offer product support. These design changes brought about the need for more sophisticated electrical distribution protection, which coincided with the early generations of electronic protective relays, including the widely employed GE Multilin and ABB circuit shield relays. Industry Leading Life Cycle Policy ABB's products are designed for continuous evolution. Over time, both older electromechanical relays and newer solid-state or microprocessor-based relays can wear down or fail in ways that are specific to their design. The combination of these efforts results in an exponentially decreasing failure rate.
