Dear Customers and Partners, As China’s National Day approaches, YT Electric would like to express our sincere appreciation to all customers, distributors and partners for your continued trust and support. Please be informed that our office will be closed for the China National Day Holiday from October 1 to October 7, 2026. During this period, responses to emails, technical inquiries and ord...
High-density data centers, semiconductor fabs, and offshore platforms expose a weakness in many silicon-based active harmonic filters (AHF) and static var generators (SVG): the correction target moves faster than the thermal design. At 20–25.6 kHz, a conventional silicon IGBT converter can correct current distortion, but switching loss, 45°C full-load temperature rise, heatsink volume, a...
Transformer Overheating from Harmonics: K-Factor vs AHF Mitigation In heavy industry, large data centers, and plants packed with VFDs and six-pulse rectifiers, a distribution transformer can run within its nameplate kVA and still develop abnormal temperature rise, oil-temperature alarms, or accelerated winding insulation ageing. The usual load-current check misses the frequency content of that cur...
Centralized or Distributed Compensation? How to Place AHF and SVG in Multi-Transformer Facilities In modern industrial complexes, continuous process plants, chemical refineries, automotive manufacturing hubs, and large commercial campuses, electrical power is distributed via multi-transformer substations (often configured as Main-Tie-Main or dual-ended secondary selective substations). A standard ...
AHF and SVG Maintenance Guide for Equipment Lifetime Modern active power quality systems—including Active Harmonic Filters (AHF) and Static Var Generators (SVG)—serve as the first line of defense for critical industrial distribution networks. Unlike traditional passive capacitor banks that contain no active switching semiconductors or microprocessors, active filters are high-density po...
Harmonic Resonance in Data Center UPS Eco-Mode: AHF vs Active Line Conditioning Hyper-scale enterprise data centers and colocation cloud facilities are under relentless pressure to optimize Power Usage Effectiveness (PUE) and reduce megawatt-scale operational electricity costs. To capture energy savings of 2% to 4% across large uninterruptible power supply (UPS) fleets, engineering managers increa...
