An innovative solution to assess the reliability of transformers by integrated transformer health monitoring
The article describes the implementation of integrated monitoring of a power transformer (PT) as a pilot project in Gujarat Energy Transmission Corporation Limited (GETCO) (Gujarat, India). It is shown how an innovative approach helped to better understand the influence of various system parameters and equipment operating conditions on its condition. Some key results obtained during the pilot project are highlighted. For example, more precise recommendations were received on the repair and maintenance of the ST, which helped to decide on the possibility of extending the operation of the ST and on the possible nearest date for its decommissioning. The article also briefly discusses how integrated condition monitoring can be applied to fleet management.
