Abstract
The development process of the gas in the transformer oil is tracked by the insulating oil on-line monitoring device.Compared with the laboratory offline data
and combined with comprehensive diagnosis and timely outage
a transformer core multi-point earthing faults is found
and the equipment health status is acquired. Accurately
the occurrence of further expansion faults and accidents are avoided.
