This European Standard covers dry type transformers from 100 kVA to 3 150 kVA intended foroperation in three phases distribution networks, for indoor continuous service, 50 Hz, naturalcooling, with two windings:− a primary (high voltage) winding with a highest voltage for equipment of 3,6 kV to36 kV;− a secondary (low voltage) winding with a highest voltage for equipment not exceeding1,1 kV.For outdoor application, special design or enclosure (enclosure with adapted IP and IKdegrees protections) should be requested.NOTE 1 This European Standard may be applied, as a whole or in part to transformers having windings with morethan one rated voltage. In this case the rated power for each coupling ratio should be specified by the purchaser.NOTE 2 For dry type transformers installed in power generating plants, additional requirements, not covered bythis European Standard, and alternative requirements may be specified.NOTE 3 For dry type transformers dedicated to wind turbines applications additive requirements are specified inEN 60076-16.The object of this European Standard is to lay down requirements related to electricalcharacteristics, dimensions and designs of three phases distribution dry type transformers.These transformers should be in accordance with EN 60076-11 for general requirements.
