Abstract

SENSOR, MÉTODO E SISTEMA PARA MONITORAR LINHAS DE TRANSMISSÃO A presente invenção refere-se a um aparelho, método e sistema para medir o campo magnético produzido pelos condutores de fase em linhas de energia com múltiplas fases. As medições do campo magnético são utilizadas para determinar a carga de corrente nos condutores. Os campos magnéticos são percebidos por enrolamentos colocados suficientemente próximos das linhas para medir a voltagem induzida nos enrolamentos pelo campo, sem tocar as linhas. Os componentes x e y dos campos magnéticos são utilizados para calcular a sag do condutor, e então os dados da sag, junto com os dados da potência do campo, podem ser utilizados para calcular a carga de corrente na linha e a fase da corrente. Os cálculos da sag da presente invenção são independentes da voltagem da linha, e das medições da corrente da linha. O sistema aplica uma rotina de ajuste computadorizada junta às voltagens medidas e amestradas nos enrolamentos para, de forma precisa, determinar os valores dos parâmetros associados com os condutores de fase aéreos.
