Chauvin Arnoux Energy

Within the Chauvin Arnoux Group, Chauvin Arnoux Energy (formerly Enerdis) specializes in fixed measurement equipment and offers a comprehensive range of products critical for monitoring and controlling the electrical distribution in nuclear power plants.

We master the design and manufacturing of products meeting the requirements of the harshest nuclear reference frameworks (resistance to aging, seismic resistance, production processes…) and we assist our Customers throughout the technical qualification phases (K3, IEEE…).

Thanks to the vertical integration of our production in our factories in France, we offer perennial equipment: developed in the 1970s, our products are installed in the first generation of nuclear power plants. For over 40 years, we have maintained these products and kept them up to date with recent standards to meet the requirements for new nuclear projects, as well as the needs of maintenance of existing power plants through ten-yearly inspections and for safety strengthening.

Our equipment is qualified for several models and generations of nuclear power plants (American, Russian, French and Chinese designs). It is designed in new projects, notably EPRs in China and the United Kingdom.
