Heavy industrial and manufacturing facilities operate in highly dynamic electrical environments shaped by cyclical loads, arc furnaces, induction heating systems, and large medium-voltage motors. VarStec engineers industrial harmonic filter banks, capacitor banks, and motor-starting solutions to address harmonic distortion, reactive power demand, harmonic resonance, switching transients, high inrush currents, and voltage sags.
Addressing Industrial
Power Grid Challenges
Capacity Optimization & Power Factor Correction
Our custom-engineered metal-enclosed capacitor banks, harmonic filter banks, and Hybrid STATCOM systems supply the reactive power required by cyclic and fluctuating industrial loads. They improve power factor, reduce utility penalties, and help maintain the required voltage profile.
Targeted Harmonic Mitigation for Arc & Induction Furnaces
To address the severe harmonic distortion generated by arc furnaces, induction furnaces, and large VFD/VSD systems, we engineer custom metal-enclosed harmonic filter banks. These systems provide targeted filtering and damping to reduce voltage distortion and prevent harmonic resonance, supporting compliance with IEEE 519, applicable IEC standards, and utility interconnection requirements.
Transient-Free Motor Starting (MotorVAR™)
Starting large synchronous and induction motors typically rated at 2,000 HP and above can cause severe voltage sags that disrupt the entire plant. VarStec’s MotorVAR™ system supplies the precise reactive power needed to start these motors smoothly while enabling full starting torque. As a plant-wide solution, MotorVAR™ can support multiple motors across a facility to avoid the need for individual solid-state starters or VFDs
How VarStec Helps
Eliminating the E-House Requirement
By supplying reactive power locally during motor acceleration, MotorVAR™ avoids the large footprint and “black-box” complexity of traditional drive systems. This eliminates the need for climate-controlled E-Houses and specialized switchgear, significantly reducing the total installed cost and physical space requirements.
System-Fit Engineering for Complex Environments
Standard designs are often not built to manage the complex constraints of heavy manufacturing. VarStec provides application-specific engineering to ensure our reactive compensation systems navigate these constraints while providing a more robust and reliable alternative to catalog equipment.
Comprehensive System Analysis & Compliance
We do not offer one-size-fits-all solutions. VarStec performs detailed motor-starting, load-flow, and harmonic analysis studies to ensure the final solution is technically correct and meets all industry requirements. This engineered approach ensures the system is optimized for the facility’s actual electrical behavior and operating objectives.
