ITU-T K.110 - Lightning protection of the dedicated transformer for radio base station
December 1, 2015 - ITU-T

This Recommendation addresses the lightning protection of dedicated transformers used to provide electrical power for radio base stations (RBSs). It contains procedures for earthing, bonding and direct lightning protection of the dedicated transformer, including protection methods for...

DS/EN 50541-2 - Three phase dry-type distribution transformers 50 Hz, from 100 kVA to 3 150 kVA, with highest voltage for equipment not exceeding 36 kV – Part 2: Determination of loadability of a transformer loaded with non-sinusoidal current
July 19, 2013 - DS

This European Standard gives to the user guidance to determine the loadability of an oil-immersed distribution transformer, as defined in and covered by EN ……….., in the case of load current with harmonic factors exceeding the maximum values allowed.

IEEE C57.144 - Guide for Metric Conversion of Transformer Standards
June 24, 2004 - IEEE

The intent of this guide is to assist the working groups within the IEEE Transformers Committee; thus, specific examples were taken from the transformer-related standards. It should be recognized that identification of general principles and procedures could have broader application....
