The pre-use dry-type transformers for distribution networks or for specific transformer users need to undergo pre-acceptance checkout by the power supply bureau or by the users.However in both of the checkout processes,due to the limitations and complexity of relevant examination technology and the users'lack of knowledge of transformers,the detection of winding materials are currently unavailable.Moreover,there exists a certain possibility of encountering trans-formers whose winding are made of aluminum or copper-clad aluminum rather than pure copper.In view of this a simple and rapid method for detecting the probability of aluminum in dry-type transformer windings is proposed,which can facili-tate promoting the pre-acceptance checkout of dry-type transformers in electric industry.
