Abstract

Un transformador de corriente de auto-corrección 100 combina un transformador de corriente 113 y electrónica de auto-calibración 115 en un dispositivo. El transformador de corriente tiene un sensor inductivo 106 con varias vueltas que son menores que un número objetivo de vueltas, para provocar que una corriente secundaria 205 inducida en el sensor inductivo sea mayor que una corriente secundaria objetivo 404 que corresponde al número objetivo de vueltas. Un circuito de medición 116 integrado con el transformador, determina una señal de error 214 que representa qué tan mayor es la corriente secundaria de la corriente secundaria objetivo y saca la señal de error. Un circuito de sumidero de corriente 129 integrado con el transformador, deriva una cantidad de corriente 216 desde el sensor inductivo, con base en la señal de error, para reducir una magnitud de la corriente secundaria para igualar la corriente secundaria objetivo. El circuito de medición y el circuito de sumidero de corriente se pueden alimentar por la corriente secundaria.
