Transformer Condition Monitoring Technology Based on Surface Acoustic Wave Passive Wireless Sensing Antenna

As the infrastructure for people’s production and life, stable operation of power facilities is very important. a key equipment in facilities, transformers have become important daily maintenance sector. In past, electric personnel mostly used on-site visual inspection to preliminarily judge whether transformer operating normally. The disadvantage this method inaccuracy. A condition monitoring technology based on surface acoustic wave passive wireless intelligent sensing system proposed overcome above shortcomings. Its working mechanism monitor oil level, temperature external ambient cooling real time. Then, status can be determined. data transmitted control center through 4G network help centrally transformer, then provide pre-alarm function abnormal conditions transformer.
