Abstract: Transformer is one of the key equipment in the power system.In practical application, the transformer fault seriously affect the operation safety, so it is of great significance to carry out automatic fault monitoring. In this paper, an on-line monitoring system architecture of transformer based on ZigBee wireless sensor network is proposed.Based on the ZigBee wireless sensor network, the platform of monitoring data transmission and data collection based on MATLAB is designed.It can be used to realize the monitoring of fault characterization parameters such as transformer winding temperature, partial discharge,gas concentration, etc. The system has the characteristics of low price,
easy implementation, and high reliability, and has certain practical value.
Key words: Power Grid transformer; Condition monitoring; Remote monitoring
