Today more than ever before in the past, control and protection system’s sophisticated technology of hydroelectric generators is essential to ensuring availability and minimizing O&M costs.

At MAS S.A we realize that flexible operations driven by increasingly variable grid demands and water management requirements introduce new parameters. Such parameters may include thermal, mechanical, and electrical stresses that were probably not considered in hydro turbine’s original design.

MAS S.A specializes in hydroelectric power generation and offers tailor made solutions based on the most sophisticated available technology.
