SVCs

Static VAR Compensator

Reliable SVC systems for dynamic reactive power compensation

Our Static Var Compensator (SVC) delivers robust and reliable dynamic reactive power compensation, optimized for high-disturbance applications such as electric arc furnaces (EAFs), and heavy industry.

Designed with thyristor-controlled and thyristor-switched components, our SVCs stabilize voltage, reduce flicker, and support grid compliance — even under severe load fluctuations. Whether you need a new system or an upgrade to an aging unit, we offer engineered solutions with full service and lifecycle support.

Key Benefits:

  1. Fast dynamic response (20–30 ms typical)
  2. Voltage stabilization under fluctuating loads
  3. Effective flicker mitigation for EAF and large motor loads
  4. Supports both inductive and capacitive compensation
  5. Enhances system stability and avoids utility penalties
  6. Field-proven in utility, industrial, and mining applications
  7. Suitable for integration into brownfield substations or system expansions
  8. Backed by Southern States' 24/7 after-sales support and long-life engineering
