Capacitor Tank-Rupture Prevention -- I2t Considerations

This paper treats capacitor tank-rupture prevention from an I²t viewpoint and provides for the extension of the time-to-rupture curves into the low current very long time energy domain commensurate with partial failure of the capacitors. The generation of the appropriate I²t curves for fuses and capacitors is presented accompanied by recommendations for the prevention of rupture utilizing expulsion and current-limiting fuses.
