T-Star solves difficult power system problems...

Our Static VAr Compensator (SVC) Systems ...Who and Why?

Plant/Corporate Engineers

Are you planning on installing new electrical loads, building a new mill or upgrading an existing mill, pump station, mining, auto shredder, or automated welding operation?

Are you unable to start your large HP motor(s)?

Utility and Electric Co-op Engineers

Do you need to avoid brownouts on power systems using "green energy" cogeneration?

Do you need to mitigate issues associated with flicker producing loads?

Would you like to save dollars and resources by reducing your wholesale power purchases?

Cost Benefit

Saves hundreds of thousands (or millions) of dollars when T-Star SVCs are “designed in” during new plant planning or plant upgrading.


  • "Strengthens" the existing primary electrical power system (4160V and above) – eliminates prohibitively expensive power system upgrades.
  • A single T-Star SVC allows starting of multiple large HP motors without VFD’s and soft starters.
  • A single T-Star SVC reduces transformer loading and maintains voltage levels during dynamic electrical loading.
  • Supports existing soft starters to get hard-to-start large HP motors to full speed. If you purchased a large HP motor that you can't get started, a T-Star SVC (or combination SVC and soft starter) is clearly the most cost-effective solution. One SVC (applied directly on the distribution primary) can accommodate multiple “problem” loads in electrical utility/co-op applications.
    • Enables increased industrial loading in low PF plant applications such as mining.
    • Eliminates flicker to prevent your electric power provider from shutting down your industrial facility – welding, arc furnaces, woodchippers, dynamically-varying industrial loads of all kinds.
    • Provides a constant steady plant bus voltage after upgrading from MG sets to VFD’s (mill applications).
    • Improves industrial plant production throughput by maintaining rotor speed during heavy loading of wound-rotor (shredder) operations.
    • Prevents brownouts in "Green Energy" applications (solar, wind, local cogeneration) – automatically compensates on a sub cycle basis as distributed generation becomes unavailable.
    • Main controller is "Smart grid-compatible."
