DANSK DS/IEC TS 60076-20 PDF

This part of IEC 60076 is applicable to transformers in the scope of IEC 60076-1. The energy performance levels given in section 6 are not applicable to the following transformers: • Transformers for high current rectifiers following IEC61378 series and IEC 60146 series. • Transformers for furnace applications • Transformers for offshore applications • Transformers for emergency or temporary mobile installations • Traction transformers for 16.7 Hz • Earthing transformers following IEC60076-6 • Transformers which cannot fulfil the energy performance requirements due to unavoidable size and weight limitations In this standard ‘transformers’ includes both separate winding transformers and autotransformers.
