Abstract :
The use of a time-division multiplier power meter as a watt transfer standard between the National Institute of Standards and Technology (NIST) and an industry standards laboratory is described. Measurements of power at 120 and 240 V, 5 A, 50 and 62 Hz, and at power factors of one and zero lagging are described. After the unit of power was transferred to the industrial laboratory, a comparison of the laboratory and NlST calibrations indicated an agreement to within 14 parts per million.<>
