Abstract

MÉTODO E DISPOSITIVO PARA ESTIMAR A FORÇA DE GRAMPEAMENTO SOBRE UM PACOTE DE ENROLAMENTO DE UM TRANSFORMADOR OU REATOR. A presente invenção refere-se a um método e a um dispositivo para estimar a força de grampeamento de enrolamento sobre um pacote de enrolamento de um transformador ou reator, o pacote de enrolamento compreendendo pelo menos um enrolamento (1) com conexões (1a, 1b) e um núcleo de ferro. O dispositivo compreende um gerador de pulso de corrente (4) configurado, um meio para suprir o pulso de corrente para o enrolamento, um sensor (6) para medir as vibrações do transformador ou reator geradas pelo pulso de corrente, e uma unidade de computação (8) configurada para calcular a dita frequência ressonante mecânica com base na medição das vibrações e estimar as forças de grampeamento sobre os pacotes de enrolamento com base na frequência ressonante mecânica calculada e uma relação predeterminada entre a frequência ressonante mecânica esperada e a força de grampeamento.
