A reactor, also called an inductor or choke, is a passive component that stores energy in a magnetic field when an electrical current passes through it.

Reactors play an important role in power electronics circuits:

  • reactive power compensation
  • harmonic filters
  • short-circuit limitation
  • motor start-up
  • neutral points
  • interphase reactors

VPI reactors are typically used for both low and medium voltage (untill 52kV). TMC develops and produces cast reactors only for special projects when the required voltage is very high.

The winding can be either copper or aluminium, while the cooling technologies can be direct/indirect water and AFWF Air-Water.

TMC focuses on iron core production, reactors with an iron core, as well as reactors with an air core or shell.
