Abstract :
As the final stage of development of a new system for impedance calibrations, a facility for calibrating standards of mutual inductance has been realized. Being based on the three-voltmeter method, this facility makes it possible to calibrate 1 mH to 100 mH standards at frequencies up to 5 kHz with uncertainties of the order of 0.01 %. An improved direct connection technique is used when routine calibrations of mutual inductors are made by means of a four terminal-pair LCR meter
