Configuration of Capacitor bank. A delta-connected bank of capacitors is usually applied to voltage classes of 2400 volts or less. In a three-phase system, to supply the same reactive power, the star connection requires a capacitor with a capacitance three times higher than the delta connected capacitor.

I expect C1, C2 and C3 in your diagram are filtering capacitors. They filter unwanted high frequencies from power line. Their impedance is low for high frequency signal and high for low frequency signal. This results in acting like a short circuit for high frequency signals. All these capacitors are in dangerous places - in the case of their
With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply. This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as

A better choice is to connect your bypass and decoupling capacitors directly to the power and ground planes, rather than to route a short trace on the surface layer. This reduces the inductance for this signal path by approximately a factor 10. In other words, your typical trace on the surface layer, with about 0.5 nH per inch of inductance, would produce a voltage droop of anywhere
If you series-connect two equal value capacitors in series, cathode-to-cathode and use only the positive lead of each cap to connect to other part of the circuits. This trick are very often seen in audio equipments.
The connection of the isolated or ungrounded systems to the ground is through distributed natural capacitance. When a line-to-ground fault occurs, the ground shorts out the capacitance of that phase, and the voltage to ground and charging currents of the ungrounded phases increase by √3.

Circuit Connections in Capacitors - In a circuit, a Capacitor can be connected in series or in parallel fashion. If a set of capacitors were connected in a circuit, the type of capacitor connection deals with the voltage and current values in that network.
Then we can see that if and only if the two series connected capacitors are the same and equal, then the total capacitance, CT will be exactly equal to one half of the capacitance value, that is: C/2.
The total capacitance ( C T ) of the series connected capacitors is always less than the value of the smallest capacitor in the series connection. If two capacitors of 10 µF and 5 µF are connected in the series, then the value of total capacitance will be less than 5 µF. The connection circuit is shown in the following figure.
