Our Founders

Paul B. Steciuk & Peter A. Steciuk

VarStec President and Senior Power Systems Engineer

VarStec Vice President and Senior Design Director

VarStec’s founders bring nearly 40 years of experience designing, applying, integrating, commissioning, and advancing medium-voltage reactive compensation equipment. Their work has helped advance the size and complexity of metal-enclosed capacitor banks, harmonic filter banks, and related power-quality equipment for large industrial, mining, and petrochemical applications involving nonlinear loads, rectifiers, harmonics, and significant power-quality challenges. That experience now guides VarStec in developing the next generation of compact, fully integrated reactive compensation equipment for increasingly demanding power-quality applications.

LEADERSHIP & ORIGINS

Solutions

VarStec applies the same core power-system principles across all industries while accounting for each site’s load profile, harmonic environment, switching duty, utility requirements, environmental conditions, and operating constraints.

Filter Banks

Engineered filtering solutions designed to provide reliable reactive compensation, power factor correction, and harmonic control for medium-voltage power systems.

Capacitor Banks

Fully integrated, metal-enclosed capacitor systems designed to provide highly reliable reactive compensation, power factor correction, and voltage support for heavily loaded medium-voltage power systems.

Hybrid STATCOM

Combines the speed of a STATCOM with the economy of switched capacitor banks or harmonic filter banks.

MotorVar

VarStec’s MotorVar^TM helps start large medium-voltage motors without the added cost and complexity of an adjustable speed drive or RVSS.

Surge Protection

Surge protection products to protect motors, generators, transformers, and other medium-voltage equipment from damaging transient overvoltages.

Industries Served

Every industry has its own operating requirements and constraints. VarStec accounts for those differences by applying sound electrical and mechanical design principles to the design and manufacture of practical, application-specific medium-voltage reactive compensation equipment.
