|Title:||Extension of Voltage Range for Power and Energy Calibrations|
|Published:||April 01, 1999|
|Abstract:||A special purpose ac voltage divider system with ratios of 600, 480, 360, 277, and 240 V to 120 V has been developed to extend the range of primary electric power calibrations from 120-600 V at 50 and 60 Hz. The developmental goal has been to realize ac voltage scaling within 55 V/V overall relative uncertainty. By employing a technique consisting of a special two-stage resistive divider compensated with an active circuit, the overall uncertainty achieved after calibration is 45 V/V.|
