Abstract： Transformer gas relays are a key component to ensure the safety of the power system，but their traditional monitoring methods face challenges in dealing with complex working conditions and early failure warning. Currently，cuting-edge technological developments in the feldofgasrelays，especially intellgentsensing technology，artificial inteligencediagnostic algorithms and predictivemaintenancestrategies，are driving the transformation of transformer protection technology towards intelligence and high reliability.These advanced technologies can effectively overcome the shortcomings of traditional relays and provide strong support for the long-term safe and stable operation of power systems.
