Harmonic Filter & Blocking Reactor

7% (189Hz) and 5.67% (210Hz)

If the operating temperature of 120°C is exceeded, the reactor circuit is disconnected by a thermal switch (included as standard).

Adjusted rating

The adjusted reactor is designed to create exactly the required output of reactive power, allowing for the internal voltage rise inside the resonating circuit formed together with the capacitor connected in the circuit. Note that exact sizing of the capacitor is necessary.

Non-Adjusted rating

The non-adjusted reactor is matched to a power capacitor with standard rating at mains voltage. This allows for additional installation of detuning reactors in existing non-detuned systems, however, it will lead to increased output to kVAr due to voltage rise inside the resonance circuit.
