Problems solved by technology

[0004] Although the transformer vibration and sound detection method is widely used in the monitoring of transformer operation status, and the technology is relatively mature, but because the vibration and sound detection method uses the vibration signal sent by the transformer, it is easily affected by environmental noise, so this method is not suitable for practical work. Unsatisfactory results are often not obtained when applied in the environment
