Potomac Engineer Presents at PowerTest

On the opening morning of NETA’s 2011 PowerTest conference, Potomac engineer, John Mayan presented his paper “The Danger in 480-Volt Systems that Disappears with Medium Voltage”. His paper presented comparative analysis of similar substation transformers operating at different voltage levels and investigates the impact of voltage on arc-flash hazard risk category. Attendees learned: how a change from high voltage to medium voltage impacts HRC; dangers associated with 480-volt systems; and how to potentially minimize cost and risk through an increase┬áin equipment voltage.
