Abstract: Electrical current sensing and monitoring methods include connecting sensing a voltage across a conductor having a non-linear resistance such as a fuse element. The current flowing in the conductor is calculated based on at least a first detected state of the sensed voltage and a thermal equilibrium characterization of the conductor.

Abstract: A first electrical response of a capacitor bank is accessed, the capacitor bank including a plurality of capacitor units arranged in a fixed spatial relationship with each other, each capacitor unit having a nominal impedance; a test electrical signal is provided to the capacitor bank; a second electrical response of the capacitor bank is measured after providing the test electrical signal to the capacitor bank; the first electrical response of the capacitor bank and the second response of the capacitor bank are compared; and whether an impedance of one or more capacitor units in the capacitor bank has changed relative to the nominal impedance is determined based on the comparison.

Abstract: Electrical current sensing and monitoring methods include connecting a compensation circuit across a conductor having a non-linear resistance such as a fuse element. The compensation circuit injects a current or voltage to the conductor that allows the resistance of the conductor to be determined. The current flowing in the conductor can be calculated based on a sensed voltage across the conductor once the resistance of the conductor has been determined.
