Determine whether the running transformer is hot or not
To judge whether a transformer is heating during operation, there are commonly used methods as follows:
(1) the method of monitoring the warm wax tablet;
(2) the hot gas flow observation method for oil immersed transformer;
(3) observe the method of chromotropic film to observe whether there is serious discoloration in the main contact area.
(4) rectifying the transformer can observe the melting of frost and snow.
(5) observe the local drying and steam in the rain.
(6) the method of live test for wax rod of dry type transformer.
(7) the method of using the thermometer to live test;
(8) ZTELEC transformer with closed light night inspection.
