Palabras clave:
Efecto Sumoto, Dieléctricos Líquidos, Movimiento EHD, Descargas ParcialesResumen
En el presente trabajo se muestra los resultados preliminares de caracterización eléctrica del efecto Sumoto. Este fenómeno aparece en una interface entre un dieléctrico liquido y aire. Cuando se aplica una alta tensión a un electrodo sumergido en el liquido, se forma un cono ascendente de aceite sobre el conductor. Este cono de fluido posee una carga eléctrica asociada. Se presenta su caracterización en términos de los parámetros siguientes: Tensión positiva C.D., forma del electrodo de baja tensión, pureza del líquido, nivel de fluido en el contenedor.Citas
