Abstract
A bridge-based mains frequency power standard has been operated at MSL for the last 16 years. Over this time there have been some improvements to the bridge components and some refinements to the procedures used for calibrating the bridge. These changes have reduced the standard uncertainty from 19 μW/W to 11 μW/W at unity power factor.
