SPHEREA: an alternative to the incumbent supplier of EDF TROPIC relays

The launch of the TROPIC industrial protection relay project has its origins in EDF’s decision to seek an alternative to AREVA, which had always supplied its TROPIC industrial electrical protection relays, but which announced in 2008 that it was no longer able to maintain these products. SPHEREA, at that time EADS Test & Services, had then decided to submit a bid in response to the request for proposals.

"We had just completed the reverse engineering for the Arinc 629 card, which is essential to our ATEC benches for testing Boeing equipment. Tektronix, its manufacturer, had just stopped producing it," recalls Stéphane Rommel, in charge of industrialisation. "This product gave us the necessary credibility with EDF, for its requirement to reverse engineer its TROPIC industrial protection relays." In 2009, the deal was on.
