MV compensation reactors 50 kvar up to 1 Mvar

Increased capacitive power consumption is observed in broad cable grids which are typical for wind farms and mining industry. Uncompensated reactive power in the system leads to many negative effects:

•    Extra fees for power factor overdrawn
•    Additional power losses in transmission lines and transformers
•    System instability due to voltage increase when grid has capacitive character

ED3KH compensation reactors are used to keep inductive character of a grid. Inductive power of a reactor reduces capacitive power, ensuring that grid operates within a proper Q/P coefficient range.

Benefits Application
  • No fees for capacitive power
  • Stable, inductive power factor
  • Reduction of active losses
  • Release of grid capacity thanks to reduction of effective value of the current
  • Reactive power compensation systems
  • Onshore & offshore wind power plants
  • Compensation of broad cable grids
  • Mining industry
