Abstract: The transformer lifespan depends on its winding temperature. The winding temperature has decisive function to insulating material temperature aging, therefore, the winding temperature measurement devices are allocated in large and medium transformer. The principle of thermometer for transformer winding was presented. The supervisory instrument must be reliable, the over temperature of transformer winding and over tolerance of supervisory instrument will influence the transformer normal operation. The matters needing attention in using of thermometer for winding were expounded.
Key words: transformer, thermometer for winding, principle of thermal analogy method, online measurement method, matters needing attention
