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.
