Abstract

Un método determina la información de temperatura asociada con una conexión de bobina de corriente en un medidor. El método incluye llevar calor desde una conexión de bobina de corriente hasta una ubicación próxima a un devanado dispuesto alrededor de un núcleo. El núcleo incluye una abertura a través de la cual se dispone una bobina portadora de corriente, el medidor mide la corriente que lleva la bobina portadora de corriente. El método también incluye medir una resistencia del devanado dispuesto alrededor de un núcleo, en donde el devanado tiene una resistencia que varía en función de la temperatura. El método incluye determinar un valor de temperatura basado en la resistencia medida y almacenar o comunicar el valor de temperatura determinado.
