HARMONIC DISTORTION

THE EFFECT OF HARMONICS IN ELECTRICAL SYSTEMS

A harmonic is defined as one of the components obtained from

The breakdown of a periodic wave in the Fourier series.The order of a harmonic is further defined as the ratio between

The frequency of the harmonic and the fundamental frequency of

The periodic wave considered.

In the case of a perfectly sinusoidal waveform (as shouldcharacterize the voltage supplied by the utility) only the

fundamental harmonic of the first order will be present, which inEurope has a frequency of 50 Hz.If a sinusoidal voltage is applied to a load, the circulatingCurrent will also have a sinusoidal waveform only in thepresence of loads with linear characteristics.In the presence of a non-linear load the current wave formwill deviate from the ideal pattern and breaking down thewave according to the Fourier theorem will show evidence of harmonics whose number and amplitude will increase withthe degree of distortion in the current waveform.The increasingly frequent use of non-linear loads in

Industrial facilities (inverters, fluorescent lamps, welders,etc.)Creates elevated distorsions in the waveform of circulating current.This is true in the case of ac/dc converters, for which the input current Theoretically displays only harmonics of the order

With a non-linear three-phase load the neutral current isnot zero and can also be larger than

the phase current because of homopolar harmonics

Unbalanced load

Unbalanced voltages are unequal voltage values on 3-phase circuits that canExist anywhere in a power distribution system. Unbalanced voltages can causeSerious problems, particularly to motors and other inductive devices.Perfectly voltage-balanced circuits are not possible in the real world. However,Assuming perfectly balanced voltages are possible, branch circuit voltages onA 480/277V supply would be exactly 277V measured at each output phaseConductor at the supply transformer. Typically, these voltages may differ byA few volts or more. It's when voltages differ excessively that problems occur.

THE EFFECT OF UNBLANCED LOAD IN ELECTRICAL SYSTEMS

Unbalanced voltages usually occur because of variations in the load.When the load on one or more of the phases is different than the other(s),Unbalanced voltages will appear. This can be due to different impedances,Or type and value of loading on each phase. Essentially, the resultingOurrent unbalance is caused not only by the system voltage unbalanceBut also by the system impedance, the nature of the loads causing the

Unbalance, and the operating load on equipment, particularly motors.Single-phasing, which is the complete loss of a phase, is the ultimate voltageUnbalance condition for a three phase circuit.

Specific values shows better impact of unbalanced voltagesAnd provide application guidance as well.The National Electrical Manufacturers Association (NEMA) in its MotorsAnd Generators Standards, defines voltage unbalance as follows:

Percent

Voltage = 100 x (maximum voltage deviation from average voltage)unbalance (average voltage)

The following example illustrates the formula. With line-to-line voltages of 460, 467, and 450, the average is 459, the maximum deviation from average is 9,and the percent unbalance equals: 100 x (9/459) = 1.96 %.




The most common symptoms of unbalanced voltages are the deleteriousEffects that impose on electric motors. Also damaging effectsOn power supply wiring, transformers, and generators.Unbalanced voltages at motor terminals cause phase current unbalanceRanging from 6 to 10 times the percent voltage unbalance for a fully loadedMotor. As an example, if voltage unbalance is 1% then current unbalance

Could be anywhere from 6% to 10%. This causes motor over current Resulting in excessive heat that shortens motor life, and hence, eventualMotor burnout

The following chart illustrates the typical percentage increases in motor lossesand heating for various levels of voltage unbalance.

With an unbalanced three-phase load the

neutral current is not zero,but it is smaller than the phase current

With a balanced three-phase load theneutral current is zero




REDUCING CARBON DIOXIDE EMISSIONS IN THE ENERGY SECTOR

Atmospheric levels of carbon dioxide (CO2) have increased steadily since the beginning of The industrial revolution and these levels are projected to increase even more rapidly asThe global economy grows. Significant climate changes are very likely associated with

Increased atmospheric concentrations of certain gases, most significantly CO2.The humanAnd ecological cost of climate changes forecast in the absence of mitigation measuresIs sufficiently large, and the time scales of both intervention and resultant climate changeResponse are sufficiently long, that prudent action is warranted now.

Inkeeping with our company mission to helpMinimize emissions and stop global warming,We constantly conduct environmental researchTo ensure our products enhance our planet.Systems improve energy has resultedTo in increase efficient of Industrial equipment,which led to a drop in thermal effects and reduceEmissions of carbon dioxide resultingFrom the consumption of energy-intensiveIndustrial equipment reduce the waste of global energy.This reduction making our air more cleaner

The basic nature of this function dictates that at ordinary temperatures, most of the levels

Up to the Fermi level EF are filled, and relatively few electrons have energies above

The Fermi level.The Fermi level is on the order of electron volts (e.g., 7 eV for copper),

whereas the thermal energy kT is only about 0.026 eV at 300K. If you put those numbers

Into the Fermi function at ordinary temperatures, you find that its value is essentially 1 up to

The Fermil level, and rapidly approaches zero above it. The illustration below shows

The implications of the Fermi function for the electrical conductivity of a semiconductor.

The band theory of solids gives the picture that there is a sizable gap between the Fermi level

And the conduction band of the semiconductor. At higher temperatures, a larger fraction of the

Electrons can bridge this gap and participate in electrical conduction.

Note that although the Fermi function has a finite value in the gap, there is no electron population

At those energies (that's what you mean by a gap). he population depends upon the product

Of the Fermi function and the electron density of states. So in the gap there are no electrons

Because the density of states is zero. In the conduction band at 0K, there are no electrons

Even though there are plenty of available states, but the Fermi function is zero.

At high temperatures, both the density of states and the Fermi function have finite values inThe conduction band, so there is a finite conducting population.

Fermi-Dirac distribution as a function of temperature

The Fermi function f(E) gives the probability that a given available electron

energy state will be occupied at a given temperature. The Fermi function

comes from Fermi-Dirac statistics andhas the form
