Three-phase resonant chokes, 3RTR 7% 440V Al type
Purpose and design
Resonant chokes are intended for use in reactive power compensation systems. They are installed in series with the capacitor bank to form a resonant circuit that protects the capacitors from overload. Such an arrangement limits the amplitude of current harmonics and reduces the risk of resonance. Resonant chokes are selected individually for each compensation stage taking into account the rated voltage of the capacitor, its rated power and the required resonant frequency.
