VarStec provides practical engineering resources designed to support system-level analysis, precise design decisions, and the long-term performance of medium-voltage reactive power systems. We believe that predictable real-world execution begins with sound engineering judgment and a deep understanding of complex grid dynamics.
This library provides essential technical resources for engineers and EPCs developing projects that require reactive compensation, harmonic filtering, and motor start solutions. Every resource is engineered in accordance with the latest IEEE and IEC standards to ensure global compliance and technical accuracy.
Access application-focused guide form specifications for medium-voltage capacitor banks, harmonic filter banks, reactors, MotorVar™ systems, and related power system studies. These documents help EPCs, consultants, and plant engineers define technically sound, standards-aligned requirements for reactive compensation and harmonic mitigation projects.
VarStec Power Sessions are technical videos, webinars, and recorded discussions focused on medium-voltage reactive compensation, harmonic filter design, motor starting, commissioning, and field application challenges. These sessions are developed to help engineers better understand practical design decisions, standards requirements, and real-world system behavior.
Download professional-grade engineering workbooks and calculation tools for evaluating capacitor switching, breaker duty, TRV, outrush, harmonic filter design, insulation coordination, and MotorVar™ motor-starting performance. These tools support preliminary design, application review, and standards-based evaluation of medium-voltage power system equipment.
VarStec Engineering Briefs provide concise, standards-based technical guidance on key medium-voltage power system topics. Each brief explains a specific application challenge, the engineering basis behind it, and practical approaches for improving reliability, safety, and System-Fit™ performance.
The Technical Q&A section provides direct answers to common and advanced questions related to power factor correction, capacitor banks, harmonic filters, switching transients, protection, motor starting, arc flash, commissioning, and hybrid reactive power systems. It is organized to help engineers quickly find practical, technically grounded information for real-world applications.
VarStec Insights includes company updates, industry trends, application commentary, and technical perspectives from the VarStec team. This section highlights what is new at VarStec while sharing practical observations on the evolving needs of medium-voltage reactive compensation, harmonics, and power quality markets.
