Ahf & Giải pháp chất lượng năng lượng SVG

Power quality made simple for Office Buildings, Trường học & Crypto Mining Farms — reduce harmonics, correct power factor, stabilize voltage, and unlock capacity.

Clean power for reliable operations and measurable ROI.

Why Power Quality Matters

Hài hòa, low power factor (PF), voltage fluctuations, and three‑phase unbalance increase losses, cause overheating, trigger nuisance trips, and shorten equipment life. Fixing these issues quickly reduces penalties, improves energy efficiency, and frees 10–30% extra capacity on existing infrastructure.
  • Lower energy and demand charges; fewer penalties
  • Cooler transformers/cables; fewer trips and downtime
  • Better performance for VFDs, UPS, Đèn LED, and sensitive loads
  • Supports compliance with IEEE 519 / GB/T 14549 objectives

FAQ

Will this help me meet IEEE 519 at the PCC?We size and configure the solution to your specified limit (VÍ DỤ., THDi ≤5–8% at the PCC), subject to proper installation and verified site measurements.
AHF vs SVG — which is most cost‑effective?If harmonics dominate, choose AHF. If you also need PF and unbalance correction, choose APF. If PF is the main issue, SVG typically offers the best value.
Can I start small and expand?Đúng. Our modular systems parallel seamlessly, so you can start with a smaller capacity and scale with load growth.
How long does installation take?Many projects complete within hours to a few days depending on switchgear, cable runs, and commissioning scope.
What maintenance is required?Minimal routine checks (filters, airflow, connections). Remote diagnostics and predictive alerts are available.
Noise considerations for offices/schools?Typical cabinet noise is 55–65 dB depending on rating and cooling; placement and ventilation design help meet acoustic targets.
