Electric power generation and consumption is a field that has seen a flurry of developments. The expansion of these technologies has created a need for protection and automation equipment to prevent grid faults, and thereby ensure a reliable energy supply.
In the last decade, the world’s electric power systems experienced several blackouts. Though the main reasons for these blackouts are known, technical progress is still lagging behind. Smart protection systems could ensure that electric power systems are not only developed, but also become more reliable.

Smart protection systems use travelling-wave based technology. The proposed solution could offer considerably better protection against grid faults than conventional systems.
Smart protections target transmission and distribution network operators all over the world. They could significantly improve electric power systems in terms of reliability, flexibility, stability margins, equipment availability, and lifetime.
