Product Introduction

Industrial Static Var Generator (SVG) for Dynamic Power Quality

Tackle low power factor and harmonic pollution at the same time. Our SVG systems and custom reactors work together to dynamically compensate for inductive or capacitive loads.

With ultra-fast response times, they lock your power factor at exactly 0.99. You get precise compensation every time, completely eliminating the risk of over- or under-compensation.

As an advanced power electronic device, the SVG uses high-speed IGBTs and smart control algorithms. It manages reactive power instantly to stabilize voltage, correct power factor, and maximize your overall grid stability.

Product Feature

Ultra-Fast & Precise Response

Outperforms traditional contactor-switched capacitors with a response time of <5ms. Instantly adapts to rapidly changing loads, ensuring your power factor stays perfectly optimized.

Bi-Directional Compensation

Delivers comprehensive power factor control for any load type. Generates both capacitive (leading) and inductive (lagging) reactive power to maintain precise grid balance.

Superior Efficiency & Stability

Built with an advanced three-level inverter topology. This minimizes switching losses and heat generation, achieving up to 98% efficiency and reducing your overall energy costs.

Full Compensation at Low Voltage

Unlike traditional capacitors, output power does not drop during voltage sags. Maintains rated current output even under low-voltage conditions, guaranteeing continuous and reliable protection.

FAQ

Q: How is an SVG better than a traditional capacitor bank?

A: Capacitor banks are slow, bulky, and can only provide fixed steps of compensation. They also risk creating resonance with your grid harmonics. An SVG is dynamic. It responds in milliseconds, provides smooth and precise compensation, and actively filters harmonics without any resonance risk. It's a smarter, safer, and more compact investment.

Q: Can this unit work if my factory voltage is unstable?

A: Yes, that is its main job. The SVG is designed to handle wide voltage fluctuations. Unlike capacitors, whose output drops with the square of the voltage, the SVG maintains its rated reactive current output even when the voltage sags. It actively supports the grid voltage to keep it stable.

Q: Do you offer both module and cabinet types?

A: We offer both. The modular unit is for panel builders who want to integrate it into their own LV panels. The cabinet type is a plug-and-play solution, fully wired and tested at the factory. You just connect the main power and CT cables.

Q: What is the expected lifespan of the IGBT modules?

A: Our three-level topology reduces the voltage stress on each IGBT. Combined with intelligent thermal management and high-quality DC-link capacitors, the design life of the power modules exceeds 100,000 hours.
