where [U.sub.nom] is the nominal voltage, [U.sub.nom] = 380 V; [lambda], cos[[phi].sub.1], v are, respectively, the power factor for the non- sinusoidal circuit, the power factor of the main harmonic and the distortion factor
This low-harmonics concept is based on a 3-level technology that lowers the total current distortion factor
THD(i) to a value less than 5% (in accordance with IEEE 519).'
Harmonics are characterized by distortion factor
(DF) that is defined as the ratio of the root-mean-square of the harmonic content to the root-mean-square value of the fundamental quantity .
Calcualtion of the distortion factor
of the panoramic radiograph.
Harmonic distortion factor
is defined as the ratio of the root- mean square of the harmonic content to amplitude of the fundamental quantity, expressed as a percent of the fundamental.
The PX8000 makes it possible to simultaneously measure the harmonic components of voltage and current waveforms as well as the harmonic distortion factor
. Harmonic measurements up to the 500th order take place in parallel with conventional voltage and current measurements.
Following Barriga et al.'s (2001) study, we tested a six-factor solution (four cognitive factors plus one AR and one PF factor) against a three-factor solution (one cognitive distortion factor
, one AR, and one PF factor), and a four-factor solution (one primary and one secondary cognitive distortion factor
, one AR, and one PF factor), and a higher-order seven-factor solution (including a cognitive distortion factor
underlying the four cognitive distortions).
Admittedly the distortion factor
in Bulgaria is lower - recorded emigration rates of between 6% and 7% compare to figures of up to 50% reported in polls of the capital Sofia - but the overarching point remains the same; immigration polls are not to be trusted.
Simulation results of six-pulse and proposed 30-pulse ac-dc converters feeding a DTCIMD load are scheduled and various quality criteria such as THD of ac mains current, power factor, displacement factor, distortion factor
, and THD of the supply voltage at PCC are compared.
This distortion factor
is then entered in to the Elcometer 550 via the menu and future readings will take account of this distortion factor
for this particular powder coating type.
Determining the active power and distortion factor
of the current and voltage is carried out in three steps:
