Dynamic Ratings is a world leader in providing monitoring, control and communication solutions for electrical power apparatus. Our business is built around sharing our extensive knowledge of the design and operation of the electrical equipment (assets) our customers manufacture own, operate and maintain.

We passionately serve customers. Our engineering, applications and project management teams provide complete solutions offering: site walks, technical applications consultation, solution design, installation, systems training and full or witnessed commissioning. Dynamic Ratings works to ensure our customers achieve the benefits they desire.

Supporting our customers goals, we are continually enhancing our products and services to provide solutions that extend the useful life of power transformers, generators, motors, circuit breakers, switchgear and cables, while improving workforce and public safety, leading to maintenance savings and ultimately providing greater economic opportunity and electrical equipment capacity.

Dynamic Ratings is a wholly owned subsidiary of the Wilson Transformer group of companies, which is the leading manufacturer of power and distribution transformers in Australia, with manufacturing joint ventures in Malaysia and Saudi Arabia.

Dynamic Ratings originated in the early 1990s when WTC developed a PLC-based transformer management system. Realizing the limitations of PLCs for this application, WTC developed a more robust hardware for use in electrical substations. The  evolution of this product platform remains ongoing.

Dynamic Ratings expanded its range of products and services in 2009 with the acquisition of Electrical Diagnostics Innovations, Inc. (EDI) from Brooklyn Park, Minnesota. This addition compliments Dynamic Ratings’ product line by providing tools for advanced transformer bushing monitoring and partial discharge monitoring in transformers, motors, generators, switchgear, and cables.

Early in 2011, Dynamic Ratings acquired the power line carrier technology from Wisconsin-based Telkonet. This product line provides secure communications over existing cables, which has applications for communications systems within switchyards and substations for generation, transmission and distribution assets.

Since establishment, Dynamic Ratings has continued its growth via organic and inorganic means, with a clear vision to be a world leader in the field of monitoring, control and communications for electrical power apparatus.

Dynamic Ratings serves customers in global marketplaces from strategic locations and via authorized Agents and representatives.

The Dynamic Ratings’ Asia office is located in Glen Waverley, VIC Australia with staff in New Zealand, Oceania. United States offices are located in Denver, CO, and Piqua, OH, with headquarters in Sussex, WI. We staff a Canadian office in Surrey, BC, a European office in Cheshire, UK, and a Latin American office in Cuernavaca, Mexico.
