Meramec

What Meramec does

Meramec Instrument Transformer Company manufactures custom instrument current transformers for the electric power industry, specializing in bushing-type CTs used in high and medium-voltage circuit breakers, power transformers, and generators. The product portfolio spans internally mounted oil-type (OBCT) and dry-type (DBCT) units, outdoor slip-over CTs (SBCT), board-mounted generator CTs (BGCT), encapsulated generator CTs (EGCT), high-accuracy revenue metering CTs (CRT-15E), and rectangular zero-sequence CTs (RELV). Core technology centers on grain-oriented electrical-grade silicon steel cores, a proprietary nitrogen-atmosphere core annealing process with automated thermal and atmospheric control, two-part epoxy edge bonding, molded resin encapsulation, and toroidal core winding to tight tolerances, with every unit tested for excitation loss, polarity, dielectric properties, turn ratio, phase angle, and ratio correction factor.

The company operates from a single integrated manufacturing facility in Cuba, Missouri, and claims to be the largest bushing current transformer manufacturer in the Western Hemisphere. Its commercial model is B2B and engineering-driven: products are custom-designed against customer operating requirements and applicable national and international standards, priced via a Request Quote (RFQ) process, and sold directly through enterprise field sales to OEMs in the HV/MV power circuit breaker and power transformer markets, as well as to the utility service aftermarket for replacement and upgrade applications including metering additions and emergency outage response.

Meramec is a wholly-owned brand within Hubbell Power Systems, the electrical infrastructure division of NYSE-listed Hubbell Incorporated, leveraging the parent's sales, marketing, and distribution infrastructure to reach global markets while maintaining specialized manufacturing operations and over 50 years of domain expertise.
