Three phase dry-type distribution transformers 50 Hz, from 100 kVA to 3 150 kVA, with highest voltage for equipment not exceeding 36 kV - Determination of loadability of a transformer loaded with non-sinusoidal current1 Scope This European Standard gives to the user guidance to determine the loadability of dry type distribution transformers, as defined in and covered by EN 505411, in the case of load current with harmonic factors exceeding the maximum values allowed.

BS EN 4311 specifies the classification of studs with a minimum tensile strength of 1100 MPa and a maximum operating temperature of 315 °C
