Data Sheet ADE9000 ENERGY ERROR OVER FREQUENCY AND POWER FACTOR
Total energies obtained from a sinusoidal voltage with an amplitude of 50% of ful scale, a sinusoidal current with a constant amplitude of 10% of full scale, a variable frequency between 45 Hz and 65 Hz, and the integrator off. Fundamental energies obtained with a fundamental voltage component, with an amplitude of 50% of full scale in phase with the fifth harmonic, a current with a 50 Hz component that has constant amplitude of 10% of ful scale, a fifth harmonic with a constant amplitude of 40% of fundamental, and the integrator off, unless otherwise noted.
