Abstract
A high voltage capacitor includes multiple capacitor packs housed in a canister. A capacitor pack status monitor includes a current sensor measuring an electric current through an associated capacitor pack and a radio transmitting a first signal representative of the electric current through a selected capacitor pack. The monitor also includes a voltage sensor measuring an electric voltage across the associated capacitor pack and a radio transmitting a second signal representative of the electric voltage across the selected capacitor pack. Electronics compute an impedance associated with each capacitor pack. Each current sensor may include a current transformer positioned around a main power line energizing a respective capacitor pack. Each voltage sensor may include a relatively large high voltage discharge resistor connected across the respective capacitor pack, and a relatively small voltage measurement resistor connected in series with the relatively large high voltage discharge resistor across the respective capacitor pack.
