Abstract
An arrangement for use in a utility meter is disclosed. The arrangement includes a meter blade coupled to a current coil. The arrangement further includes a current sensor that includes a winding about a core. The current sensor is in a current sensing relationship with the current coil. The winding has a resistance that varies as a function of temperature. The arrangement further includes a processing circuit that is operably coupled to receive a measurement signal from the winding. The processing circuit is configured to determine a DC component of the measurement signal, determine the resistance of the winding based at least in part on the determined DC component, and cause a value representative of the determined resistance to be displayed or communicated to an external device.
