Abstract
La presente invencion se relaciona con un sensor de corriente para un dispositivo electrico incluyendo un circuito primario en donde fluye una corriente primaria. Un circuito magnetico comprende dos elementos identicos en forma de "U" entre los cuales estan colocados dos pernos para los intervalos de aire. Un circuito secundario incluye dos bobinas semejantes de una forma cilindrica, montadas en serie y rodeando los intervalos de aire en donde estas dos bobinas se fabrican de manera continua con solamente una operacion de enrollamiento sin ninguna conexion electrica entre ambas bobinas. El enrollamiento del circuito primario rodea una de las dos bobinas. El sensor se disena de manera que pueda adaptarse a varias escalas nominales de corriente primaria variando el numero de pasajes del circuito primario dentre las bobinas, el numero de enrollamiento del circuito secundario y el espesor de los intervalos de aire.
