Protection scheme devices may cover the following elements: (a) external and internal short circuit; (b) over- and under-voltage at the connection point to the transmission system; (c) over- and under-frequency; (d) demand circuit protection; (e) unit transformer protection; (f) back-up against protection and switchgear malfunction. 4. The relevant TSO and the transmission-connected demand facility owner or the transmission-connected distribution system operator shall agree on any changes to the protection schemes relevant for the transmission-connected demand facility or the transmission-connected distribution system, and on the arrangements for the protection schemes of the transmission-connected demand facility or the transmission-connected distribution system.
