Choke

as per standard ČSN EN 60 076 - 6

  • Compensation – a choke determined for parallel connection into the system with the purpose of compensating the capacity current
  • For the restriction of the current – a choke determined for serial connection into the system in order to restrict the current in case of defective states
  • Damping – a choke determined for serial connection with condensers for the restriction of the built-up current in the course of switching
  • Filtration – a choke determined for serial or parallel connection with condensers with the purpose of reducing, blocking or filtration of harmonious or commutation frequencies
  • Smoothing – a choke determined for restricting the circulation of harmonious currents and transient overcurrents in steady networks
