| Abstract: |
Many standards laboratories do not have the capability to calibrate their standard power meters used for low frequencies (50-60Hz). It is difficult to refer them to DC standards because in general, they only respond to AC signals. This paper shows a new system, based on known equations, that permits the calibration of AC wattmeters. The precision of this method depends only on the precision of one resistor and a RMS voltmeter. Both can easily be traced to DC standards. [ABSTRACT FROM AUTHOR] |
