Frequently Asked Questions
1. What are the primary applications of this series of power capacitors?
This series is specifically engineered for low-voltage AC power systems operating under 1KV at 15Hz to 60Hz. They are primarily applied for power factor correction and harmonic filtering in industrial and commercial electrical networks.
2. What capacity and voltage ratings are offered in the FACS-BC series?
The series provides rated voltage choices between 400VAC and 460VAC with capacity selections ranging from 20 Kvar up to 60 Kvar, designed for 50Hz/60Hz working frequencies.
3. How does the self-healing technology improve capacitor reliability?
The self-healing dielectric can automatically isolate fault points and restore insulation in the event of voltage breakdown or local faults caused by external factors, ensuring uninterrupted and safe operation without catastrophic failure.
4. Why is a series reactor recommended with this harmonic filtering capacitor?
Connecting the capacitor in series with a detuning reactor creates a tuned circuit that avoids parallel resonance, suppresses harmonic current magnification, and safely filters targeted harmonic frequencies in the power grid.
5. What environmental conditions are required for safe installation?
The capacitors require installation altitudes ≤2500m, operating temperatures between -20℃ and +65℃, humidity of 20%~90% (under 40℃), and barometric pressures between 79.5Kpa and 106Kpa, in surroundings free of explosive media, corrosive gases, conductive dust, violent vibration, or rain/snow erosion.
6. What built-in safety features are integrated into these capacitors?
The units feature double-safety protection mechanisms and integrated discharge resistors to rapidly dissipate residual charge when the capacitor is powered down, ensuring personnel and equipment safety.
