Designed for Modern Electrical Challenges

An SVG compensates for leading reactive power by operating in inductive mode: it injects lagging VARs into the system to counter the surplus leading VARs caused by capacitive loads, restoring the power factor toward unity. It solves problems that capacitor banks and legacy SVC systems can't handle.

  • No more over/under voltage from load swings
  • Accurate compensation, ms-level response, no over-compensation or under-compensation
  • Stable power factor—even with solar or wind input
  • Avoid overloading transformers and generators
  • Prevent costly downtime and improve uptime

Reactive Power Explained: Why Feigin SVG Matters

When the power factor is leading (i.e., current leads voltage), it's caused by a capacitive load pushing reactive power back into the grid. Most grids are designed for inductive loads, so this can lead to:
  • ⚠️ Overvoltage at the point of common coupling
  • ⚠️ Unstable voltage regulation
  • ⚠️ Capacitor switching issues or harmonics
  • ⚠️ Reverse VAR flows stressing equipment
In short: excess leading VARs can be just as harmful as lagging ones.

An SVG (Static Var Generator) works like a controllable reactive power source. When the grid is too capacitive, the SVG:
  • 🔹 Operates in inductive mode and injects lagging VARs
  • 🔹 Neutralizes excess capacitive VARs
  • 🔹 Moves system power factor toward unity
In simple terms:
  • ✅ If the grid is capacitive → SVG acts inductive
  • ✅ If the grid is inductive → SVG acts capacitive
It adjusts in real time—no mechanical switching needed.

Leading power factor is common in systems with:
  • ✅ Many capacitive devices or overcompensated power factor correction
  • ✅ HVDC links or electronic converters
  • ✅ Data centers with active correction modules
  • ✅ Wind farms exporting reactive power
SVGs are essential for these environments—they provide instant, dynamic VAR correction without mechanical switching, unlike traditional capacitor or reactor banks.
