Frequently Asked Questions (FAQ)

Q1: What are the main dielectric and filling materials used in these shunt capacitors?

Flair shunt capacitors utilize high-grade metalized film as the dielectric material and are encapsulated with heat-convertible resin inside a hermetically sealed stainless steel shell.

Q2: How does the internal safety protection mechanism work?

Each element is equipped with an individual safety protection device and internal fuse. In the event of a fault, the failed element is promptly isolated from the circuit to prevent explosion or short-circuit hazards.

Q3: How quickly does the discharge resistor lower the terminal voltage?

With the fixed-connection discharge resistor installed, the residual voltage is reduced below 75V within 3 minutes after power disconnection (available upon request).

Q4: What internal connection configurations are available for different series?

The FACS-BC3 model features non-connected internal elements suitable for delta configurations via fling-cut switches, the FACS-BC3Y provides an internal wye (star) connection, and the FACS-BC model is designed for standard 3-phase systems.

Q5: Can these capacitors be used in harmonic filtering applications?

Yes, the FACS-BC series harmonic filtering capacitors can be connected in series with detuned or tuning reactors to effectively filter frequency harmonics in power networks.

Q6: What are the standard operating temperature and altitude ratings?

The capacitors are rated for an ambient operating temperature range of -20°C to +50°C and can operate at altitudes below 2000 meters.
