Delta connection of capacitors requires two bushings. Since there is no connection to ground, the capacitor bank cannot be a ''sink'' for any ground currents or zero sequence currents. Individual branch of the delta connected capacitor need to be protected against phase-phase short circuit by a current limiting fuse. Star Connected Capacitor Bank
