Advanced Static Var Generator (ASVG)

Next-Generation Power Quality Correction for Modern Electrical Networks

An ASVG (Advanced Static Var Generator) is a high-performance power quality device designed to stabilise electrical networks by providing dynamic reactive power compensation and active harmonic mitigation. Unlike traditional capacitor banks or step-based systems, an ASVG reacts instantly to load fluctuations, making it ideal for facilities that operate variable speed drives, robotics, automation systems, EV chargers, and other sensitive or rapidly-changing loads.

LPINZ offers a premium ASVG solution that delivers reliable performance and exceptional value, perfectly suited for commercial, industrial, and utility-grade applications across New Zealand and the Pacific.

How an ASVG Works

• Real-time reactive power compensation
  Continuously monitors the electrical load and injects the precise compensating current needed to maintain a near-unity power factor — even under rapidly changing operating conditions.
• Active harmonic mitigation
  Detects and cancels harmonic currents in real time, reducing THD to <5% for improved system stability and compliance with power quality standards.
• Ultra-fast IGBT control
  Achieves response times in the tens of microseconds, ensuring seamless performance during sudden load transitions and protecting sensitive equipment.

Key Features & Benefits

✓ Reduce Operating Costs
Correcting the power factor improves energy efficiency and reduces unnecessary loading on transformers, switchgear, and cabling.

✓ Improve Equipment Reliability
Cleaner power means fewer malfunctions, reduced overheating, and longer lifespan for motors, drives, and automation systems.

✓ One Device — Multiple Functions
The ASVG provides both dynamic power factor correction and harmonic filtration, eliminating the need for separate systems.

✓ Ideal for Modern Industrial Sites
Perfect for facilities with large numbers of VSDs, CNC machines, data centre loads, or renewable/EV infrastructure where power quality is critical.
