ecosine? harmonics are a serious problem 4 power quality in times of blackouts and brownouts. power quality has become the buzzword of entire industries. while definitions diverge, nobody disputes its importance and the consequences of poor power quality. often, electric utilities end up in the line of fire of frustrated customers. however, many disturbances C like electromagnetic interferences or harmonics C are not attributable to the utility company, but to the user of the electric power supply and the nature of the connected loads. creation of harmonic currents and voltages. modern consumers of power, such as variable speed drives for motor controls, switch-mode power supplies in home electronics, or ballasts in fluorescent lamps, significantly contribute to energy saving and a more efficient use of electricity. however, the nature of their operation causes a non-sinusoidal current to be drawn from the grid. this non- sinusoidal current consists of the fundamental 50 or 60hz wave and its integer multiples, the harmonics. harmonic currents flow through system impedances, transformers, reactors etc., and cause harmonic voltages. as a result, the supply voltage of other consumers connected to the same branch of the grid is distorted, raising questions about equipment service life, function, and reliability. non-linear load (six-pulse recti?er) rl 1 rl 2 rl 3 ll3 ll1 ll 2 line impedance vl1 vl2 vl3 power source power line r load r es r c out voltage distortions: propagate throughout the system and affect sensitive loads current distortions: overload the electric infrastructure, affect power lines and equipment vo ltage (phase-neutral ) curren t
5 ecosine? harmonics are a serious problem
ecosine?  harmonics have a serious impact. harmonics reduce system efficiency and waste precious energy. harmonic currents overload and overheat electric installations, distribution transformers, breakers, fuses, conductors etc. they cause premature system ageing or generate the requirement for an increase in electric system capacity. harmonics overload capacitor banks in var compensation equipment and cause malfunctions in electronic controls, disturbances in sensitive medical devices, or crashes in communication networks. financial consequences. unfortunately, harmonics mitigation is considered an expensive nuisance. very often it is not budgeted for in the planning phase of a project. however, the decision to ignore this issue can potentially lead to a much more substantial cost impact. the capacity of electric installations may have to be increased. equipment may fail prematurely. disturbances may cause production downtime. utility companies may even issue power quality violation penalties to the point where an entire factory has to be temporarily disconnected from the grid.
ecosine?  international requirements. international power quality standards such as ieee 519- 1992, en 61000-3-12, en 50160, en 12015, g5/4 or as 2279 define C among many other things C distortion limits and recommend harmonics mitigation practices. ieee 519-1992 is probably the most widely accepted set of recommendations that defines maximum permissible current and voltage distortion percentages at the point of common coupling (pcc) under full load conditions. the applicable limit depends upon the system loading parameters, i.e. the relation between the maxi - mum short circuit current (i sc ) and the maximum demand load current (i l ) at the pcc. ieee 5  9-  992 current distortion limits [%] harmonic order (odd harmonics) i sc /i l tdd <   h<   h<23 23h<35 35h <20 5.0 4.0 2.0 1.5 0.6 0.3 20<50 8.0 7.0 3.5 2.5 1.0 0.5 50<100 12.0 10.0 4.5 4.0 1.5 0.7 100<1000 15.0 12.0 5.5 5.0 2.0 1.0 >1000 20.0 15.0 7.0 6.0 2.5 1.4 maximum harmonic current distortion in percent of i l (even harmonics are limited to 25% of the odd harmonic limits above). ieee 5  9-  992 voltage distortion limits [%] please consult the published standards or local utility codes for more details about your individual harmonics mitigation requirements. special applications (hospitals, airports) 3 general systems applications 5 dedicated systems (100% non-linear loads) 10
ecosine? ecosine? C getting a grip on harmonics  reliable harmonics mitigation. the best place to eliminate harmonics is right at their source, i.e. at the individual non-linear load. only then can the propagation of harmonic currents and voltages throughout the system be avoided. schaffner ecosine? filters are uniquely able to master this challenge. they provide a low impedance path for harmonic currents required by the rectifier, thus significantly reducing the amount of harmonics flowing through the electric distribution system. as a result, the non-linear load virtually draws a sinusoidal current from the grid. in a typical motor drive system, the total harmonic current distortion (thid) is reduced to well below 8% at any load condition, and to <5% at full load. compliance with the toughest total demand distortion (tdd) levels according to table 10-3 of ieee 519 is therefore ensured. high performance C not only at full load. often manufacturers promote filter perfor - mance only at full load because light load conditions can be a challenge in terms of both harmonics mitigation and capacitive current. schaffner ecosine? filters not only guarantee the thid rating of 8% maximum over the entire load range, but also limit the amount of capacitive current in all conditions. an external capacitor disconnect switch can easily be installed, if capacitive current under light load conditions has to be suppressed. you can obtain more information on this subject from the schaffner ecosine? application note. load [%] z line = 0.2% z line = 3.0% 8 7 6 5 4 3 2 1 0 0 20 40 60 80 100 120 140 160 thid [% ] load [%] z line = 0.2 to 3.0% 1.2 1.0 0.8 0.6 0.4 0.2 0.0 0 20 40 60 80 100 120 140 160 cos (phi)
9 ecosine? ecosine? C getting a grip on harmonics cost and energy savings. schaffner ecosine? filters reduce harmonics and ensure that a clean sinusoidal current is drawn from the grid. both true rms and peak current are reduced in the process, thus lowering the burden on the electric installation. transformers, conductors, fuses, breakers etc. experience less electric and ther - mal stress, and can therefore be downsized already in the planning phase. in an existing installation, the capacity of the distribution transformer can be utilized more efficiently, and more electric consumers (e.g. motor drives) can be operated without investments in electric system upgrades. current voltage (phase-neutral) voltage (phase-neutral) current without schaffner ecosine? with schaffner ecosine? current current i in a rms (for power 5.5kw) i in .5a rms (for power 5.5kw) thid 92 % (for r sce 50) thid 4.0 % pwhd 3 % pwhd 5.2 % individual harmonics 5th C 4 % individual harmonics 5th C 2.0 % th C 5 % th C 2.2 % th C 3 % th C 2.0 % 3th C 5 % 3th C .4 % voltage voltage u in 40v rms (phase-phase) u in 40v rms (phase-phase) thvd 4.4 % (for i sc /i l 50) thvd 0.2 % (for i sc /i l 50) example with 5.5kw drive linke seite conductor size with ecosine tm without ecosine tm amp rating of breaker s, fuse s, etc . n o. of drives on given transformer 65% 100% 65% 100% 150% 100% linke seite conductor size with ecosine tm without ecosine tm amp rating of breaker s, fuse s, etc . n o. of drives on given transformer 65% 100% 65% 100% 150% 100% linke seite conductor size with ecosine tm without ecosine tm amp rating of breaker s, fuse s, etc . n o. of drives on given transformer 65% 100% 65% 100% 150% 100% ecosine? 9
ecosine? 0 equipment longevity, reliable production uptime. because of their unique design, ecosine? filters add impedance to the supply, thus providing all the benefits of traditional schaffner ac line reactors. in motor drive applications, for example, they eliminate nuisance tripping, and protect the rectifier and dc-link capacitors from mains transients. longer equipment service life and reliable operation of mission-critical applications reduce cost of ownership and help safeguard profits. simply plug-and-play. schaffner ecosine? filters are black boxes with three input and three output connectors. they can easily be incorporated into existing designs without requiring an in-depth system analysis or highly trained specialists. ecosine? filters do not attract harmonics from other parts of the system and do not cause system resonances. they have been designed to operate smoothly with dc-link chokes and emi filters installed in the same system. a superior inductor design and advanced thermal management result in the most compact filter package on the market today. where traditional harmonics mitiga - tion approaches require large standalone cabinets, the compact and light-weight design of ecosine? allows for filter integration right in the electric cabinet next to the motor drive. straightforward filter selection. schaffner ecosine? filters are available for 50hz (fn 3410 series) and 60hz (fn 3412 series) power grids. the ideal filter can easily be selected by determining the actual total power rating of the load (e.g. motor drive) to be connected to the filter. alternatively, the filter can also be selected by the total specified motor drive input current (arms) before filter ins tallation. it is important to avoid over-specification of the filter because it operates best close to full load.
ecosine?  two or more filters can be paralleled in case the total input power of a given load exceeds the largest available product. please consult the schaffner ecosine? application note for more details about filter selection, installation, and application. mains ecosin e non-linear load 1: 30kw/400v ac non-linear load 2: 75kw/400v ac fn 3410-210-40 (110kw/400v ac ) main s ecosine ecosine non-linear load : 300kw/500v ac 2x fn 3410-260-99 (2x 160kw/500v ac ) mains ecosin e non-linear load 1: 30kw/400v ac non-linear load 2: 75kw/400v ac fn 3410-210-40 (110kw/400v ac ) main s ecosine ecosine non-linear load : 300kw/500v ac 2x fn 3410-260-99 (2x 160kw/500v ac ) ecosine? filters are designed to be installed at the individual non-linear load. however, they can also reduce harmonics for multiple loads in parallel. if multiple loads are connected to one filter, the filter needs to be matched to the total resulting input power.
