@conference{10902/19392, year = {2020}, month = {6}, url = {http://hdl.handle.net/10902/19392}, abstract = {Nowadays, power quality is a challenge for the distribution companies since the new energy policies are directed to a distributed generation system with power electronic based technologies. The reduction of distribution transformers capability when supplying nonsinusoidal load currents has a major impact within capacity reduction in distribution networks produced by technical losses. IEEE Std C57.110-2018, EN- 50464-3 and EN-50541-2 define procedures to derate transformers when supplying nonsinusoidal load currents. The aim of this paper is to compare these procedures through a real case distribution transformer that suffers problems due to high levels of current distortion.}, organization = {This research was funded by the “Ministerio de Ciencia, Innovación y Universidades – Agencia Estatal de Investigación” grant number “RTC-2017-6782-3”, the European Union FEDER funds with name “LOcalización de averías, monitorización de estado y Control en redes de bAja TEnsión—LOCATE” and the Horizon 2020 Program by the European Comision with project reference No 864579, H2020-LC-SC3-2019-ES-SCC.}, publisher = {The European Association for the Development of Renewable Energies, Environment and Power Quality (EA4EPQ)}, publisher = {Renewable Energy & Power Quality Journal (RE&PQJ), 18(6), 747-752}, publisher = {18th International Conference on Renewable Energies and Power Quality (ICREPQ’20), Granada}, title = {A comparative between IEEE and EN in the transformer derating when supplying nonsinusoidal load current.
