A digital protective relay for power systems includes a memory location for storing
information entered by an operator concerning the operation of the relay. Conventional
reports of the relay will include a reference to such operator-entered information.
This information will include particular actions taken by the operator relative
to the relay, as well as notes made by the operator on particular actions and/or
entry of and changes to the relay settings. The entered information can be conveniently
retrieved by the operator.
