Abstract

В настоящей заявке описана дуговая плавильная система 10 и способ мониторинга или получения длины электрода дуговой плавильной системы 10. Система 10 содержит по меньшей мере один электрод, устройство измерения тока, сконфигурированное для измерения тока в электроде во время работы системы, и устройство обработки данных. Устройство обработки данных сконфигурировано для определения колебаний величины тока в электроде, измеряемого устройством измерения тока на протяжении некоторого периода времени, и получения характеристики колебаний величины тока, которая является показателем длины электрода. Получение характеристики колебаний величины тока осуществляют на основе, по меньшей мере, колебаний величины тока, определенных на протяжении указанного периода времени.
