Abstract: An arc mitigation apparatus for an air insulated switchgear includes: a flap; a switch; and a control mechanism. The flap is installable in a wall of a compartment of a medium voltage switchgear. When the flap is installed in the wall of the compartment of the medium voltage switchgear, the flap permits when open air and/or gas passes through the flap from inside the compartment to outside the compartment. When the flap is installed in the wall of the compartment of the medium voltage switchgear, the flap is movable from a closed position to an open position due to a pressure difference between an inside of the compartment and an outside of the compartment. The switch activates based on movement of the flap. The control mechanism sets a flap threshold pressure for the flap with respect to the pressure difference that will move the flap.

Abstract: One exemplary method for message suppression comprises: providing first and second rules, each having one or more preconditions and a conclusion, wherein the first rule also has a suppressed-by attribute and at least one of the second preconditions is suppressing; evaluating the one or more first and second preconditions; identifying the first rule as true or false; displaying the message of the second rule if all of the second preconditions are met; identifying the first rule as suppressed if the second rule is named in the suppressed-by attribute; and inhibiting the message display of the suppressed rule or routing the message to second display. The system can comprise: a database containing knowledge of the production unit; a user interface, and at least one precondition, a suppressed by attribute, and one or more rules each having a conclusion and at least one suppressing precondition; an inference engine; and a display.
