Protection common (PROT_COMMON)
The contact states of the circuit breaker (CB) and the disconnector (DS) provided are grouped
in the protection common function (PROT_COMMON) and are used in a number of relay
applications to decide conditions. The PROT_COMMON function also examines whether a line
is dead (de-energizing), as the PROT_COMMON has an under-voltage detection (UV) relay.
The PROT_COMMON function is operated as the common function.

Note: The PROT_COMMON function is feasible in entire models, which can be enumerated
in the IED ordering number. For more information, see Appendix: Ordering .
