La resistencia del devanado en los transformadores cambiar\u00e1 debido a espiras en cortocircuito, conexiones sueltas o contactos deteriorados en los cambiadores de tomas. Independientemente de la configuraci\u00f3n, las mediciones de resistencia se realizan normalmente fase a fase y las lecturas se comparan entre s\u00ed para determinar si son aceptables.<\/p>\n\n\n\n

\u2161: \u00bfQu\u00e9 m\u00e9todo se utiliza para medir la resistencia del devanado?<\/strong><\/p>\n\n\n\n

La resistencia de los bobinados puede medirse directamente con un \u00f3hmetro. Otro m\u00e9todo consiste en calcular la resistencia midiendo la corriente que pasa por cada bobinado, utilizando un amper\u00edmetro A, cuando se aplica una tensi\u00f3n y se mide con un volt\u00edmetro V.<\/p>\n\n\n\n
