Task

When a small hydroelectric power plant is coupled to the public power grid, the power inverter must be equipped with a grid and system protection device that continually checks the grid quality and immediately decouples the system when a fault is detected. In this way, unintentional isolated operation is prevented, thereby avoiding a dangerous situation for maintenance personnel. Manufacturers of inverters require grid and system protection that fulfills the various standards of different countries with a single unit.
