Harmonic detection and filtering - Schneider Electric

9.2 Specific Schneider Electric products9.2.1 Passive filtersE95293-38-MPassive filters are made up of inductors and capacitors set up as resonant circuitstuned to the frequency of the harmonic order to be eliminated. A system maycomprise a number of filters to eliminate several harmonic orders.General characteristicsVoltage400 V three phasePower ratingUp to 265 kvar/470 A for the 5 th order filterUp to 145 kvar/225 A for the 7 th order filterUp to 105 kvar/145 A for the 11 th order filterEnclosurePrisma9.2.2 Active filters of MGE UPS SYSTEMSPassive filter.General characteristicsVoltage400 VConditioning capacity 20 to 120 A rmsper phase (A rms)Conditioned harmonic Orders 2 to 25, complete spectrum or selected orderscurrentsHarmonic attenuationLoad THDi / Upstream THDi greater than 10 at rated load onconditionerE95294-32-MFunctionsDisplacement power-factor correction7-language alphanumeric displayDiagnosis and maintenance systemParallel connectionRemote controlCommunications interface JBus/RS4859.2.3 Hybrid filtersActive filter of MGE UPS SYSTEMS.Hybrid filters combine the advantages of a passive filter and a SineWave activeharmonic conditioner in a single unit.E95295-32-MGeneral characteristicsPassive filter5 th order harmonicsActive harmonic conditioner20 to 180 AVoltage400 V three phaseReactive energy compensationUp to 265 kvarHarmonic orders conditioned 2 to 25Total harmonic currentUp to 440 AEnclosurePrismaHybrid filter.49
