OUP - ELECTRIC MACHINERY AND TR - ELECTRIC MACHINERY AND TRANSFORMERS Organization: OUP
Date: 2000-07-20
Description: This voltage change is made to reduce the electrical losses along the length of the transmission line. Even though a transformer does not convert mechanical energy into electric energy or vice versa, its study is essential because it plays a major role in the transmission and distribution of electric energy.
DS/EN 61378-1 - CONVERTOR TRANSFORMERS - PART 1: TRANSFORMERS FOR INDUSTRIAL APPLICATIONS Organization: DS
Date: 2012-01-10
Description: NOTES 1 For some convertor applications, it is possible to use common distribution transformers of standard design. The use of such standard transformers in the special convertor applications may require a certain derating.

SNZ - AS/NZS TR IEC 61000.3.13 - ELECTROMAGNETIC COMPATIBILITY (EMC) PART 3.13: LIMITS – ASSESSMENT OF EMISSION LIMITS FOR THE CONNECTION OF UNBALANCED INSTALLATIONS TO MV, HV AND EHV POWER SYSTEMS Organization: SNZ
Date: 2012-03-26
Description: • Unbalanced installations connected line-to-neutral can also draw zero-sequence currents which can be transferred or not into the supply system depending on the type of connection of the coupling transformer. The flow of zero-sequence currents in a grounded neutral system causes zero-sequence unbalance affecting line-to-neutral voltages.
