Abstract
This paper describes the improvements made to the National Research Council of Canada (NRC) Watt-VA Transfer Standard and to the AC source, which are used to support the NRC Traveling Standard Program. With these improvements, NRC clients can now calibrate on-site the voltage, current, active, reactive, and apparent power functions of their standards for rms voltages up to 600 V and rms currents up to 50 A.
