Os profissionais envolvidos na fabricação, avaliação, aplicação e especificação dos Conjuntos de Manobra e Controle de Potência (CMCPs) em Baixa Tensão (BT), utilizados na quase totalidades dos sistemas elétricos industriais, estão presenciando um processo de evolução resultante da revisão da principal família de normas técnicas internacionais relativa a este tipo de equipamento. A norma brasileira...
O uso de Conjuntos de Manobra e Controle de Potência (CMCP) nos sistemas elétricos industriais (SEI) típicos das indústrias petroquímicas, tanto de média quanto de baixa tensão, se depara com diferentes desafios, associados a sua especificação e operação, para se obter soluções que garantam a qualidade da energia elétrica a ser distribuída. Muito destes problemas estão relacionados aos seus componentes,...
The Brazilian Petroleum and Chemical Industry had basically used MV power assemblies based on ANSI / NEMA for many years. But, in the last three decades, due to the Brazilian Standard Association orientation, the users and manufacturers have been changing their philosophies to the IEC culture. As it has been an everyday increasing of the opportunity and also the need of medium voltage electrical power...
The Brazilian Petroleum and Chemical Industry has been facing an ever increasing use of dedicated generation facilities. The use of turbo-generators coupled to gas or steam turbines to partially or totally supply, the electric needs of petrochemical units, has resulted in problems, especially when interconnected with local utility companies.
