Medium-voltage equipment

Variable frequency drive Triol AT27 Series

AT27 medium-voltage multilevel frequency converter is constructed to accomplish frequency control of the speed in cage both asynchronous and synchronous motors. The drive is connected directly to a 6 kV supply and can spread up to 6 kV supply to the load. Variable frequency drive (VFD) may be used at plants with thermal power, mills, water supply facilities, for oil and chemical industries, and at mining and iron-and-steel plants.

Advantages of the applying of the AT27 VFD:

  • lower power consumption;
  • launch high-starting-torque motors;
  • enhance the reliability and extend the service life of motors;
  • enhance the reliability and extend the service life of machinery driven by motors;
  • eliminate water hammers in a piping system;
  • decrease the rate of equipment failure;
  • reduce costs for repairs and maintenance;

Operating modes

There are two modes of operation provided by AT27 VFD while controlling electric motors:

  • Manual
  • Automatic
