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 ...
SVG Reactive Power Compensation: Beyond PF Correction For decades, plant electrical engineers and facility managers viewed reactive power compensation through a single, narrow lens: avoiding utility low power factor penalty surcharges. Traditional solutions—primarily fixed capacitor banks and automatic power factor correction (APFC) panels—were designed solely to supply bulk capacitive...
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...
Installing an Active Harmonic Filter (AHF) or Static Var Generator (SVG) requires more than simply choosing current or kVAr ratings. In facilities with multiple transformers or bus sections, physical placement directly determines compensation performance. Deciding between one large centralized unit at the main bus or several smaller distributed units near individual loads depends on your electrica...
