Abstract

Un controlador suplementario (132, 144) para un buje de fibras de vidrio (102) realiza activamente calentamiento y enfriamiento de un segmento conectado (104, 106, 108) del buje (102), que de otra forma se controla por un controlador primario (122). En una modalidad, el controlador suplementario (132, 144) realiza calentamiento mediante inyeccion de corriente en un segmento de buje conectado (104, 106, 108) y enfriamiento mediante desviacion de corriente desde o alrededor del segmento de buje conectado (104, 106, 108). Operaciones de arranque inicial y compensacion puede realizarse sin activacion del controlador suplementario (132, 144). En otra modalidad de la invencion el controlador suplementario (132, 144) calienta un segmento de buje (104, 106, 108) al inyectar corriente en fase con corriente del controlador de buje primario (122) y enfría el segmento de buje (104, 106, 108) al inyectar corriente fuera-de-fase con corriente del controlador de buje primario (122).
