Successful energy transition of electrical networks!

A comprehensive offering of innovative solutions for monitoring and optimizing electrical networks, helping to foster contractualization between the actors.

Our strengths in the transmission and distribution sectors

    We have mastered the design of products with critical functions for harsh environments

    Development of products meeting the stringent requirements of the technical reference frameworks in terms of metrological accuracy (MID, IEC 60688), signal analysis (IEC 61000-4-30), reliability (life span, etc.) and ruggedness (transformer substation environments, etc.).

    Innovation lies at the heart of the development approach underpinning our offering

    A significant proportion of our sales revenues is invested in research and development to propose appropriate innovations for the issues encountered in monitoring and optimizing electrical networks.

    In collaboration with the major players in the sector, we support the investigations and set up demonstrators, which are crucial for validating a technical solution before rolling it out.

    This approach is completed by our active participation in the industrial standardization committees.

    We have been assisting network managers in the development of critical functions for decades

    A particularly broad range of products covering all your metering, measurement and electrical network analysis needs, and which can be tailored to handle the specific issues encountered by network managers.

    This offering of products and solutions takes into account the constraints of migration in terms of specific installation features or protocol choices made over the years, thus facilitating the switchover between the roll-outs of different generations or technological levels.
