摘要： Predictive maintenance systems and methods are described. A method includes measuring environmental conditions using a plurality of sensors within the IED, processing the environmental measurements to determine long-term exposure factors representing historical operating conditions of the IED, applying a reliability model to the long-term exposure factors, determining a numerical measure of IED life based on the long-term exposure factors and the reliability model, comparing the numerical measure of IED life to preselected boundary values, and signaling if the numerical measure of IED life is outside of the preselected boundary values.

摘要： A module for an electrical distribution system is provided. The module includes a socket board electrically coupled to the electrical distribution system. A plurality of sockets is mounted on the socket board. Each socket defines a port. A sensor is positioned within each port and is electrically coupled to the socket board. The sensors are configured to carry at least one of a primary current and a secondary current. A metering component is electrically coupled to the socket board and configured to measure current carried by the sensors. A communication module is electrically coupled to the metering component and in communication with a monitoring device. The communication module is configured to transmit metering data to the monitoring device.
