SVG and AHF Components: What Determines Accurate and Long-Term Performance? A 400 V plant may install two power-quality cabinets with the same rated current and expect the same result. Months later, one follows peak load while the other derates, produces more acoustic noise, or leaves compensation error at the point of common coupling (PCC). The difference lies in the sensing chain, ...
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...
