    Frequently Asked Questions (FAQ)

    Q What materials are used for the dielectric and filling in Flair Shunt capacitors?

    These shunt capacitors feature a metalized film dielectric and are filled with a heat convertible resin, ensuring solid construction and reliable performance.

    Q How does the built-in safety protection device work?

    Every capacitor element is mounted with a safety protection device. In the event of a failure, this device isolates the failing element from the circuit, protecting the capacitor from explosion or short-circuit failures.

    Q What are the specifications of the capacitor's discharge resistor?

    The capacitors are equipped with a fixed connection discharge resistor. Upon request, it is designed to safely decrease the voltage below 75V within 3 minutes after the power is cut off.

    Q What are the environmental limit requirements for installation?

    The capacitors are designed to operate in ambient temperatures ranging from -20°C to +50°C and are suitable for installations at altitudes below 2000 meters.

    Q How do the FACS-BC3, FACS-BC3Y, and FACS-BC models differ in application?

    The FACS-BC3 features unconnected internals, generally used for triangle connection angles in fling-cut switches. The FACS-BC3Y has a wye (star) connection internally. The FACS-BC is a harmonic filtering capacitor designed to be connected in series with a reactor to filter harmonics in the power system.
