Evaluation of the audible noise level on distribution transformers using the Sound Pressure Method

This paper presents the results of audible noise measurements on ten no-load distribution transformers, using the sound pressure method. The tests were conducted in the Audible Noise Laboratory of Universidad del Valle, according to the requirements described in the Colombian Technical Standard NTC...

The tests allowed to verify the conformity of the product in respect with the audible noise limits established in the Colombian Technical Standard NTC 5978. In addition, it was possible to identify the effect on noise emissions of two transformers after variating the voltage in the power source. Results show that the noise level emitted by the transformers under test was considerably lower than the limits established in the standard, and was significantly affected by the voltage of the source supply.El artículo presenta los resultados de las mediciones de ruido audible a diez transformadores de distribución sin carga, usando el método de presión sonora. Las pruebas se realizaron en el Laboratorio de Ruido Audible de la Universidad del Valle, según los requerimientos descritos en la Norma Técnica Colombiana NTC 5979, y permitieron verificar la conformidad del producto con los límites de ruido establecidos en la Norma Técnica Colombiana NTC 5978. Además, se logró identificar, en dos transformadores, el efecto en las emisiones de ruido al realizar variaciones de voltaje en la fuente de alimentación. Se encontró que el nivel de ruido emitido por los transformadores bajo prueba es considerablemente inferior a los límites establecidos en la norma y que se ve significativamente afectado por el voltaje de la fuente de alimentación.application/pdfapplication/xmlengengUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/6051/5587https://revistas.uptc.edu.co/index.php/ingenieria/article/view/6051/6408Revista Facultad de Ingeniería; Vol. 26 No. 45 (2017); 71-82Revista Facultad de Ingeniería; Vol. 26 Núm. 45 (2017); 71-822357-53280121-1129Audible noise measurementBackground noiseDistribution transformerSound pressure levelSound pressure methodMedición de ruido audibleMétodo de presión sonoraNivel de presión sonoraRuido de fondoTransformador de distribuciónEvaluation of the audible noise level on distribution transformers using the Sound Pressure MethodEvaluación del nivel ruido audible en transformadores de distribución usando el Método de Presión Sonorainvestigationinvestigacióninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a341http://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/access_right/c_abf258http://purl.org/coar/access_right/c_abf2Mina-Casaran, Juan DavidNavas, Diego FernandoEcheverry Ibarra, Diego Fernando001/14174oai:repositorio.uptc.edu.co:001/141742025-07-18 11:53:44.215metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
