REE, IPTO, Spain, GreeceThis document describes the best practices for protection schemes considering security of supply and safety of persons and equipment. It describes typical protection schemes and setting criteria to ensure system security across the interconnected European System at extra high voltage or high voltage – and in special cases even other voltage levels. The paper mainly addresses protection of the transmission lines. The document could serve also as reference for common principles, methods and procedures’, concerning protection engineering and it tries to provide the necessary background for new operational procedures. Technical solutions mentioned in this document are not considered mandatory. They are mentioned as mainly complying with the set of presumed protection principles. Alternative technical solutions can be adopted following a thorough study provided they are technically and financially justified, lead to the same or better overall performance and comply with the national grid code, the applied national and international Standards.
