Distribution Equipment Modernization to Reduce Arc Flash Hazards

This paper discusses a practical approach to allow personnel safe access to switchgear while maintaining Pulp & Paper mill processes, specifically in existing electrical distribution system unit substation installations where a main breaker was not incorporated into the original design. Various component configurations were evaluated prior to a final solution being implemented. Modernization of existing equipment was determined to be the most efficient and cost effective solution allowing mill personnel to work safely on switchgear during periods of mill production.
