1 DETUNED INDUCTORS FOR PF IMPROVEMENT CAPACITORS Electrical supply systems harmonics is like a cancer on supply systems and causes extreme bad effects on the supply system component and connected electrical apparatus. This too, without one knowing about it. These harmonic currents & voltages are generated due to the modern day non-linear loads like variable speed drives, UPS, induction & arc furnaces, LED lamps and electronically operated CFL s and other fluorescent lamps, etc. APPLICATION: Detuned Inductors for PF Improvement s s put on supply lines play a vital role when the effect of harmonic is considered. Normally capacitors causes: Enhances the harmonics. Gets itself deteriorated causing lower VAR compensation. bursting causing human safety issues. Resonance on supply system causing excessive over voltage and over current. Enhancement in short circuit fault currents. Despite these adversities, capacitors are needed to improve supply system power factor (D-PF). Designed according to the basic system odd-harmonic currents of 5th, 7th, 11th, and 13th Order as: I5 = 50% max., I7 = 25% max., I11 = 12.5% max., I13 = 5% max. (Others on special request) TECHNICAL SPECIFICATIONS: Frequency 50 Hz (60Hz on specific made to order) Voltage V AC 3 Phase Line to Line TAS DETUNED INDUCTORS give effective solution to all these above problems and allows safe usage of capacitors to improve the power factor. FEATURES Protection to capacitors against harmonics Reduces harmonic distortion Reduces power losses High harmonic load handling capacity Has a high linearity to avoid magnetic saturation for higher crest factors of waveform. Convenient mechanical design for mounting Long lifespan Temperature protection in all 3 phase windings Insulation strength Linearity Rating 5 to 100 KVAr s Cooling Natural Cooling 3kV 50 Hz for 1min 5mA tripping P-P,P-E 3% error of normal inductance value up to 130% of rated current Detuning/Filtering % voltage drop Core Ambient Temperature Insulation Class 6%, 7% & 14% Enclosure IP-00 Multi Gap Silicon Steel Phase Iron 50 C Max Temperature protection F (155 C) 3 phases Thermal Switch, 130 C NC type in all three phase windings
