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. These demanding applications impose significant harmonic distortion, reactive power demand, and high inrush currents on the plant power system, often leading to production interruptions, equipment stress, and costly utility power factor penalties.
Addressing Industrial
Power Grid Challenges
Capacity Optimization & Power Factor Correction
Our custom-engineered metal-enclosed capacitor banks and harmonic filter banks manage the fluctuating reactive power demands of heavy industrial operations. By delivering precise, highly reliable power factor correction, we help facilities optimize overall system capacity, stabilize voltage profiles, and eliminate costly utility penalties.
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 dampening to reduce voltage distortion and prevent harmonic resonance, ensuring strict compliance with IEEE 519, IEC, and utility interconnection standards.
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 meet all industry requirements. This engineered approach ensures the system is optimized for the facility’s actual electrical behavior and operating objectives.
