This paper discusses the implementation of an Ethernet communications network in a ring that connects substations in a closed communications loop at a large industrial facility. Data are transmitted at protection speeds and must be dependable for industrial power system operation and maintenance applications. The redundant electric power system Ethernet communications network is used for a supervisory...
“Network”, in this industry, has traditionally referred to the electrical power distribution network. Today, the term could easily apply to communication networks, which are becoming almost standard in the electrical power infrastructure. The role of communication networks has evolved from rudimentary data collection to, in some cases, becoming the centerpiece of complex wide area distributed data...
Low-voltage motor control centers (MCCs) are numerous and consume a large portion of maintenance and operator interaction in an industrial power distribution system. The extensive human interaction with these low-voltage (less than 1,000 V) circuits makes a low-voltage MCC a location of significant potential hazard. The large number of low-voltage MCC circuits results in significantly more human interface...
