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.
