Abstract: An assembly includes a cabinet having an interior and a door to gain access to the interior. An intelligent electronic device (IED) is within the interior of the cabinet and includes inputs providing electrical connections to the IED, pushbuttons to provide user input to the IED, a display module including a display, a component, and a timer circuit. The timer circuit powers the component OFF or places it in a reduced power state when not in use after a certain amount of time. A switch is associated with the door and is electrically connected to at least one of the inputs so that when the display module is powered OFF or in the reduced power state and when the door is opened, the switch causes a signal to be sent to the timer circuit to cause the timer circuit to power the component fully ON.

Abstract: Among other things, one or more techniques and/or systems are provided for monitoring an operating condition of an electrical component, such as electrical switchgear. In one example, temperatures associated with an electrical conductor connection within the electrical component may be evaluated against one or more expected temperatures curves derived from a linear regression model to determine whether the electrical conductor connection has failed or is starting to fail. In another example, temperature readings may be monitored to determine whether a temperature reading at one location is out of sync with temperature readings at other locations. An electrical conductor connection associated with a location of the out of sync temperature may be determined as faulty. In another example, a Euclidean distance model and/or a correlation coefficient model may be used to identify a faulty electrical conductor connection. In this way, failure and/or potential failure of the electrical component may be predicted.
