Capacitors should be connected in star with their star point is earthed. This arrangement reduces Phase voltage to each unit by root 3 and thus the voltage withstand capability of each unit. The star point in this arrangement can be earthed with Capacitor Bank body through Oil tank inside the bank which is directly earthed with the Body. Most of the time suppliers suggest above arrangement.
