  • Bus condition monitoring system
    Patent number: 8981945
    Abstract: A method and system is disclosed for monitoring switchgear. The current supplied to the main bus is measured. The current flowing through a plurality of feeder circuits is also measured. The temperature of the main bus at one or more nodes is measured, wherein a node is a connection point between the main bus and each feeder circuit. The current flowing through one of the nodes is determined by subtracting the current flow through each the feeder circuit upstream from the node, from the current supplied by the input circuit. An alarm condition is determined if the temperature at a node exceeds a predetermined temperature value for a given current flow through the node. The alarm condition is thereafter displayed to a switchgear operator.
