This Harmonization Document covers transformers from 50 to 2 500 kVA intended for operation in three-phase distribution networks, for indoor or outdoor continuous service, 50 Hz, immersed in mineral-oil, natural cooling, with two windings:
- a primary (high-voltage) winding with a highest voltage for equipment equal to 36 kV;
- a secondary (low-voltage) winding with a highest voltage for equipment not exceeding 1,1 kV.
NOTE 1: This document may be applied, either as a whole or in part, to transformers immersed in a synthetic insulating liquid.
NOTE 2: This document may be applied, either as a whole in part, to transformers having windings with more than one rated voltage. In this case the rated power for each rated voltage shall be specified by the purchaser.
