It operates based on the principle of electromagnetic induction and is an indispensable part of modern power transmission and distribution networks. Transformer fault detection refers to the use of a series of technologies and methods to monitor and assess the health status of transformers in order to identify potential problems or faults that have already occurred.

This approach cannot perform real-time detection before a fault occurs, making it difficult to comprehensively assess the transformer's condition, identify potential problems in advance to prevent faults, and easily lead to equipment downtime, affecting operational continuity. Furthermore, once a fault occurs, not only are maintenance costs high, but it may also cause safety accidents, threatening the safety of operators, making it quite inconvenient to use.
