GGJ Low Voltage Power Factor Correction Capacitor Cabinet | LV
Reactive Power Compensation Cabinet
1. Overview
The GGJ Series Low Voltage Reactive Power Compensation Cabinet (Capacitor Cabinet) is an advanced power-saving solution designed
for 0.4kV low-voltage distribution systems. By automatically
tracking and compensating for reactive power, the GGJ cabinet
effectively improves the Power Factor (PF), reduces line losses, stabilizes system voltage, and eliminates
penalties from utility companies for low power factors.
It is widely utilized in industrial manufacturing plants,
commercial buildings, infrastructure projects, and areas powered by
10-35kV to 0.4kV distribution transformers.
2. Key Features & Benefits
Intelligent Automatic Tracking: Equipped with a smart microcomputer controller that automatically
switches capacitor steps on/off based on the actual reactive power
demand, ensuring the power factor stays consistently above 0.95.
Flexible Protection Ratings: Available in IP30 and IP40 protection degrees, perfect for indoor industrial environments and
switchrooms, providing reliable safety against dust and accidental
contact.
Premium Component Selection: Can be integrated with world-renowned brands or top-tier Chinese
domestic brands for circuit breakers, contactors, and controllers
according to client specifications.
Comprehensive Protection Mechanisms: Built-in safeguards against over-voltage, under-voltage,
over-current, short circuits, and harmonic distortion to ensure the
longevity of the capacitors.
Harmonic Suppression (Optional): Can be configured with detuned reactors (e.g., 7%, 14%) to
suppress harmonics and protect capacitors from overheating in harsh
electrical environments.
