Three-phase compensation reactors ED3K

Increased capacitive power consumption is observed in the systems with LED light sources, UPS, impulse power supplies and broad cable grids. 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

ED3K compensation reactors are used to keep inductive character of a grid. Inductive power of a reactor is added to 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 current
  • Reactive power compensation systems
  • Server rooms
  • Compensation of broad cable grids
  • Light & heavy industry
