Presente no dia a dia das equipes de manuten\u00e7\u00e3o de m\u00e9dia e alta tens\u00e3o, esta dica apresenta a diferen\u00e7a conceitual dos termos:<\/p>\n

\u201cDescarga Parcial\u201d e \u201cCorona\u201d s\u00e3o termos normalmente relatados nas \u00e1reas el\u00e9tricas e de manuten\u00e7\u00e3o, s\u00e3o comumente confundidos como sendo termos similares. Eles t\u00eam em comum o fato de n\u00e3o causarem de imediato um caminho completo no diel\u00e9trico para a corrente el\u00e9trica.<\/p>\n

De acordo com a IEEE, uma descarga parcial \u00e9 uma descarga incompleta ou \u201cparcial\u201d que ocorre entre isolantes e tamb\u00e9m entre condutor e isolante. Diferentemente, uma descarga plena \u00e9 aquela que transp\u00f5e o espa\u00e7o entre condutores, ocasionando o que conhecemos como falha el\u00e9trica, por formar uma ponte condutiva.<\/p>\n

J\u00e1 o Corona ocorre quando os gases adjacentes a um condutor energizado ionizam e produzem descargas normalmente vis\u00edveis. Desta forma, descargas parciais dentro da parede isolante n\u00e3o pode ser chamada de corona.<\/p>\n

Acesse nossa p\u00e1gina de Manuten\u00e7\u00e3o Preditiva<\/a> e entre em contato com nossa equipe para mais informa\u00e7\u00f5es sobre o monitoramento de descargas parciais e diagn\u00f3sticos de predi\u00e7\u00e3o. Avalie as vantagens de paradas n\u00e3o programadas, reduzindo custos na manuten\u00e7\u00e3o de equipamentos e aumentando a efici\u00eancia do processo produtivo.<\/p>\n
