60886-EN version: 1.0 2 Presentation, references Variable speed drives Altivar Machine ATV320 Option: line chokes Presentation Line chokes, also known as line reactors, provide improved protection against overvoltages on the line supply and can reduce harmonic distortion of the current produced by the drive. The recommended chokes limit the line current. They have been developed in line with standard IEC 61800-5-1 (VDE 0160 level 1 high-energy overvoltages on the line supply). The inductance values are de ned for a voltage drop between 3% and 5% of the nominal line voltage. Values higher than this will cause loss of torque. The use of line chokes is recommended in particular under the following circumstances: b Line supply with signi cant disturbance from other equipment (interference, overvoltages) b Line supply with voltage imbalance between phases > 1.8% of nominal voltage b Drive supplied by a line with very low impedance (in the vicinity of a power transformer 10 times more powerful than the drive rating) b Installation of a large number of frequency inverters on the same line b Reduction of overloads on the cos j correction capacitors, if the installation includes a power factor correction unit The prospective short-circuit current at the point of connection of the drive must not exceed the maximum value indicated in the reference tables (see page 60882/2). The use of chokes allows connection to the following line supplies: b Max. Isc 22 kA for 200/240 V b Max. Isc 65 kA for 380/500 V References Drive Choke Reference Line current without choke Line current with choke Reference Weight U min. (1) U max. (1) U min. (1) U max.
