Abstract
Dry type transformer plays an irreplaceable role in the distribution network. The winding of the dry-type transformer is casted with the insulating material and only the necessary sub-joints are exposed. Therefore, it is hard to dissemble the dry type transformer, which makes it difficult to identification of the winding material. Thus, a set of identification system for winding copper or aluminum material of dry type transformer was developed based on the principle of thermos electromotive force. The temperature characteristics of thermoelectric force was tested of the different capacity and different material winding, the thermoelectricity characteristics of the high voltage and low voltage winding of different winding materials dry type transformer were studied. Witnessed inspection in Guangdong Province China proved that this method applied to the identification of winding material is effective.
