Facilities with unusual load profiles, strict utility constraints, or highly sensitive processes can be poorly served by one-size-fits-all equipment. An improperly matched solution can expose the power system to harmonic resonance, damaging switching transients, inadequate voltage support, and unnecessary equipment stress. VarStec applies system-fit engineering to match the solution to the actual application.

Custom Medium-Voltage Power Quality Solutions

Custom-Engineered System-Fit Solutions

Specialized applications may require unusual electrical ratings, footprint, environmental construction, switching, protection, or harmonic performance. VarStec designs the equipment around those specific requirements.

Filter Design Based on Real System Data

Where harmonic performance is critical, VarStec develops harmonic filter designs using field measurements and detailed system modeling. Filter topology—including C-high-pass, high-pass, H-Type, or notch—along with tuning, damping, component ratings, and reactive power capacity is selected to meet the facility’s harmonic mitigation and power factor correction objectives.

Solutions Matched to Physical & Environmental Constraints

Specialized facilities often involve unusual footprint limitations, retrofit conditions, high-altitude installations, or demanding environmental conditions. VarStec designs equipment around the specific installation site, accounting for conditions including dust, heat, altitude, and corrosive atmospheres.

How VarStec Helps

Representative Specialized Applications

VarStec provides engineered reactive compensation and harmonic mitigation for diverse specialized sectors, including:

  • Pulp & Paper: Managing massive VFD-driven rolls and processing equipment that generate significant harmonic distortion.
  • Glass & Fiberglass Manufacturing: Supporting the high-impact reactive power demands of electric melting and boost systems.
  • Water & Wastewater Treatment: Supporting large pump starts in remote or municipal environments to prevent system-wide voltage sags.
  • Research & Test Facilities: Providing precise power quality for variable or high-impact testing loads that exceed standard utility limits.
  • Automotive & Heavy Packaging: Mitigating voltage fluctuations caused by large-scale robotic lines and high-speed conveyor systems.

Reliable and Economic Design Approach

A one-size-fits-all approach may appear simpler at first, but it often leads to compromised performance and unnecessary long-term costs. VarStec evaluates technical tradeoffs to develop the most economically sound solution for your actual application.

Collaborative Engineering from Concept through Delivery

VarStec works directly with the project team throughout the design process to confirm requirements and review system conditions. Backed by more than 30 years of power systems experience in medium-voltage reactive power compensation and harmonic filtering, we help ensure the final solution is technically correct, buildable, and aligned with the facility’s operating goals.
