Abstract The false alarm of light gas in oil-immersed power transformer has brought trouble to the on-site operation and maintenance personnel to accurately judge the real health status of transformer, and even the unnecessary shutdown of transformer due to misjudgment has occurred. This paper aims to study a new type of intelligent gas relay to realize real-time and accurate monitoring of gas volume in transformer gas relay, thus effectively identifying the light gas alarm situation, ensuring the safety of personnel and equipment, and achieving the purpose of finding potential faults of transformer as soon as possible.
