Filter reactors are applied in conjunction with capacitor banks to create resonant circuits tuned to unique harmonic frequencies, efficiently trapping and removing them within the method.

item variety: Filter Reactors (Tuned or Detuned) are required. These reactors are created not simply for their fundamental frequency inductance but in addition to manage harmonic currents and possibly increased thermal stresses. They variety element of a larger harmonic filter financial institution.

3.3. Fault present-day Limiting

Most important functionality: in a few community configurations, specifically in close proximity to technology sources or exactly where system impedance is reduced, potential fault currents can exceed the ranking of downstream equipment (like circuit breakers). Series or special forms of shunt reactors can be employed to introduce further impedance through fault conditions, restricting the fault current magnitude.
