What RITZ Instrument Transformers does
RITZ Instrument Transformers GmbH is a Hamburg-based German manufacturer of low, medium, and high voltage instrument transformers, fully insulated busbar systems (SIS), DUROMER cast resin components, and electronic measuring transformers and sensors for the electrical power industry. Founded in 1945 (with the RITZ Measurement Transformers entity established in Hamburg by Dr. Hans Ritz in 1956), the company is controlled by the RITZ Foundation (Ritz-Stiftung), a non-profit established in 1989 by Liselotte Ritz to support Alzheimer's disease research. RITZ employs over 1,500 people across nine locations in Germany (Hamburg, Kirchaich, Dresden, Wirges), Austria (Marchtrenk), Hungary (Kecskemét), China (Shanghai), the USA (Hartwell/Lavonia and Waynesboro, Georgia), and the UAE (Dubai sales office).
The company's product portfolio spans conventional electromagnetic instrument transformers, electronic measurement transformers (including Rogowski coil-based current sensors, EGIW electronic voltage transformers with optical data transmission, and the award-winning EMVI 4005 DC/AC current converter), HVDC solutions, generator current transformers (IRBT), and space-saving combined transformers (Kombiwandler). Core technology differentiators include proprietary DUROMER cast resin formulations, high-precision measurement capabilities (current up to 24 kA, voltage up to 90 kV, frequencies 0–10 kHz for current and 0–150 kHz for voltage, accuracies from 0.1%), and in-house high-voltage testing facilities rated to 400,000 V AC and 50,000 A. The company maintains ISO 9001, ISO 14001, ISO 50001, ISO 17025, IRIS, and AEO-F certifications.
RITZ generates revenue primarily through direct B2B hardware sales of customized transformer and busbar solutions to electric utilities, grid operators, power generation companies, railway operators, and industrial customers in the electrochemical, environmental technology, and automotive sectors. Pricing is project-based rather than list-priced, and go-to-market relies on direct enterprise sales supplemented by trade show participation (EXPOMIN 2025, VDE Zählerfachtagung, Hitachi Supplier Days). Group revenue reached EUR 150 million in 2022 and is projected to exceed EUR 200 million in 2024, driven by global grid investment, HVDC/renewable energy demand, and the reopening of the Waynesboro high-voltage plant.
