Detailed in an instrument catalog, a power quality analyzer has the following specifications: Voltage (V): 600 V range, accuracy ±1% of reading Current (I): 1 – 500 A, accuracy ±1.5% of reading Power factor (PF): accuracy ±2% of reading Using the formula: P=V×I×PF√3, (8) Calculate the systematic uncertainty in power measurement as a percentage of reading due to the measurement device for measured values of 480 V, 50.0 A, and a power factor of 0.83. (12) In logging data with a high sampling rate, the calculated standard deviation of large number of readings are 4.00 V, 1.00 A, and 0.02 for the power factor, while the mean values are 480 V, 50.0 A, and a power factor of 0.83. Determine the random uncertainty of the measurements, at a 95% confidence level. (5) What is the total uncertainty in the power measurement?
