Abstract :
The paper describes a measurement system, which is now used as a transfer device for the National Research Council of Canada (NRC) Travelling Standard Program. The system is based on two sampling voltmeters and a computer used for data acquisition and analysis. The equipment is used on-site with an ac source and a new 12-position pulse-frequency comparator to provide traceability for the standards maintained by Canadian electrical utilities and electricity meter manufacturers. The accuracy of the system is better than 30 parts in 10/sup 6/. The repeatability of the errors before and after an on-site calibration is generally better than 15 parts in 10/sup 6/.
