“…Another of the company's mills had already applied the switch-over-breaker solution [4], and it had worked well. The new switches would be equipped with maintenance settings group capability applied at the direct-acting trip unit monitoring, and capable of being powered from, a set of secondary side current sensors.…”

prehensive account of a mill-wide project to bring a more than 30-year-old market pulp mill into compliance with NFPA 70E requirements and to mitigate arc-flash hazards to reasonable enough levels to allow effective maintenance. The project spanned three years and was completed in 2011. The major activities to be discussed (and through which the project had to progress) include the decision to initiate, data collection or re-creation, and update of single-line diagrams; creation of a database and software model, short-circuit analysis, multiple upgrades, or replacements to address over-dutied equipment;arc-flash analysis, protection/coordination changes to address let-through energy, equipment upgrades or replacements to address let-through energy and mitigate arc-flash hazards; equipment labeling; and training of personnel. © photodisc T
