Abstract :
In the paper, a method of two voltmeters for measurement of the frequency characteristic of shunt is described. In this scheme two voltages and phase angle between them on almost equal shunts are measured to determine phase angle between current and voltage of one of shunts. In analysis of errors, it has been found out that this method has practical meaning at phase angle between shunts higher than few degrees, where accuracy is better than 5-10-3 .
