ENERGY ERROR OVER FREQUENCY AND POWER FACTOR

Total energies obtained from a sinusoidal voltage with an amplitude of 50% of full scale, a sinusoidal current with a constant amplitude of 10%

of full scale, and a variable frequency between 45 Hz and 65 Hz. Fundamental energies obtained with a fundamental voltage at 50 Hz, with an

amplitude of 50% of full scale in phase with the fifth harmonic, a current that has constant amplitude of 10% of full scale, and a fifth harmonic

with a constant amplitude of 40% of fundamental, unless otherwise noted.
