Abstract :
WITHIN THE PAST DECADE much attention has been directed to increasing both the accuracy and speed of testing and calibrating single-phase a-c watt-hour meters. The availability of high accuracy transfer instruments has made possible the measurement of alternating current to an accuracy of 0.02 per cent.
