Abstract :
A set of resistive voltage dividers has been designed for low phase angle errors. The dividers were made for a wideband power measuring systems to cover voltages up to 1000 V. The phase angle errors of the dividers have been verified in a step-up procedure using two sampling voltmeters. Except for the highest ranges the phase angle errors are within a few /spl mu/rad at 50 Hz and within /spl plusmn/ 50 /spl mu/rad at 1500 Hz.
