Smart Grid

The intelligent electricity network (Smart Grid) is the backbone of the energy system. Our energy system is amidst a radical transition, as millions of electric vehicles hit the roads and Terawatts of renewable energy capacity are installed in our grids. Smarter equipment is needed for the Smart Grid to provide reliable integration of intermittent renewable energies and distributed energy resources. LEM improves the grid by measuring electrical parameters allowing control rooms to automate, monitor remotely and share real-time equipment data.
