Abstract

TRANSFORMADOR DE INSTRUMENTO COM LINHA DE ENERGIA A presennnte invenção refere-se a um transformador de instrumento (10) para medir propriedades de eletricidade em uma linha de energia (38) . O transformador de instrumento inclui uma seção de cobertura (18) e uma seção de base (20). A seção de cobertura inclui o primeiro segmento de núcleo (24) encapsulado em um primeiro invólucro(26) formado de resina polimérica . A seção de base inclui um segundo segmento de núcleo (44) com um enrolamento de baixa voltagem (54) todos os quais são encapsulados em um transformador de voltagem (14) todos os quais são encapsulados em um segudo ivólucris (46) formado de uma resina polimérica . Quando a seção de cobertura e a seção são presas juntas, o primeiro segmento de núcleo se une ao segundo segmento de núcleo, desse modo formado um transformador de corrente (12) tendo um núcleo formado a partir dos primeiros e segundo segmentos de núcleos. Um método para fazer o transformador de instrumento ainda compreede a conexão da seção de cobertura como a seção de base para formar uma passagem (36) através da qual o condutor de alta voltagem (38) pode se estender.
