Page 4: Attentions
Attentions Please read carefully the Instructions for the transformer winding deformation tester! Operators must read carefully the Instructions before use. The tester is applicable to testing of transformer winding deformation with frequency response method. Equipment irrelevant to the tester cannot share power supply terminal with the tester. Power supply of the system must be provided with reliable grounding to prevent the risk of electric shock. -

Generally, system abnormalities may be eliminated by restart of system software. Please do not use the system in rainy and foggy days as it is not water-proof. Put the tester into its packing case when not used and keep the packing case level. The scrapped equipment must be handled according to requirements of national laws and regulations or handed to the Company for handling. -
Page 6: System Introduction
System Introduction The transformer winding deformation tester is used for power transformer with voltage grade of 6kV and above and other transformers with special purpose. The power transformer is inevitably vulnerable to impulse of various fault short-circuit current or physical collision in the process of operation and transportation and the transformer windings may lose stability under the powerful electro-dynamic force exerted by such short-circuit current, which could result in permanent deformations such as local distortion, swell or dislocation and will severely affect safe operation of the transformer. -
