Abstract
As for the earthing heat fault of 35 kV dry type reactor in two 500 kV substations
the finding of defects by infrared temperature measurement and fault diagnosis by way of auxiliary test are introduced. The reason of heat by both loop current and eddy current is analyzed;the corresponding countermeasures and preventive measures are proposed. The suggestion on technical supervision of the earthing of dry type reactor is given from such aspects as material selection
construction and acceptance etc.
