Franksville test lab

Eaton's Franksville Test Lab, located within the Thomas A. Edison Technical Center in Franksville, Wisconsin, is a materials, high power and voltage testing facility for the use of Eaton Electrical and outside clients. The Franksville power test lab is accredited to ISO/IEC 17025 by the American Association for Laboratory Accreditation.

Eaton’s Thomas A. Edison Technical Center is located in Franksville, Wisconsin. This 113,000 square foot facility is located on 135 acres of land in the southeast corner of the state, just south of the city of Milwaukee.

This facility is where our engineers and scientists test and develop the products and technology to transform and regulate power delivery in medium voltage power distribution systems. The focus is on high-voltage and high-power testing, materials development, and new product development for medium-voltage electrical distribution products.

  • Electrical labs: The 500 MVA motor generator, along with the 9 MVA direct-connect power capabilities at a satellite lab, allows Eaton to conduct regular high-power testing. Test capabilities include the high power lab with capacity up to 500 MVA, the high voltage labs with 1 MV impulse and 200 kV AC dielectric testing, and large scale powered environmental aging.
  • Materials development lab: Here, we conduct materials testing and accelerated aging simulations. Our technologists have years of expertise in dielectric materials, paints and coatings, polymers, metallurgical, thermal and environmental exposure. Many of these scientists and engineers also represent Eaton on industry standard committees and contribute their expertise toward updating electrical standards.

Thomas A. Edison Technical Center High Power Lab Quality System

The Thomas A. Edison Technical Center High Power Lab quality system is designed to manage, operate and maintain quality control procedures to satisfy the requirements of ISO/IEC 17025. In addition to internal audits, A2LA surveillance audits are conducted to ensure the continuous suitability and effectiveness of the quality system and to maintain our accreditation and registration status. 

Accreditations and Registrations 
ISO/IEC 17025

ISO/IEC 17025 is a quality standard which outlines the general requirements for the competency of testing and calibration laboratories. It ensures that the test lab has adequate equipment to perform its testing or calibration tasks and the test lab has adequate laboratory personnel with the competence to perform the testing. 

The Thomas A. Edison Technical Center Lab is Accredited to ISO/IEC 17025 by the American Association of Laboratory Accreditation.
