Abstract :
The phase angle error of the output voltage of resistive shunts may depend on a number of stray impedance components. These components have been estimated for some shunt designs. Their total contribution has been measured by a LCR meter method and compared to a step-up procedure. The agreement between the different methods, for measureme nt of phase angle difference of two shunts, was within a few murad at 1500 Hz
