Figure 1 is used to illustrate how a grounded capacitor bank can interfere with the ground fault protection system of a resistive grounded system. The main concern arises when a capacitor fails as shown in Figure 1 by the "X". Since medium voltage capacitors fail shorted, a faulted capacitor is like applying a line to ground fault on the facilities
EMI from Capacitor Heatsinks and What You Can Do About It
This effectively creates two capacitors in parallel, which reduces the total stray capacitance. Some commercially available heatsinks will contain this type a built-in thermal washer. This odd-shaped heatsink has a unique resonance structure and can radiate at a variety of frequencies, especially when it receives a displacement current …
However, AC signals have much less reactance, so they can pass through the decoupling capacitor and get shunted to ground. These capacitors provide a low impedance path for high-frequency signals (which represents the noise) on the power supply, thus cleaning up the DC signal. This is how the decoupling capacitor decouples AC signals from DC ...

What is a decoupling capacitor and how do I know if I need one?
What is a decoupling capacitor (or smoothing capacitor as referred to in the link below)? How do I know if I need one and if so, what size and where it needs to go? This question mentions many chips needing one between VCC and GND; how do I know if a specific chip is one? ...
8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. ...

Is it healthier for a capacitor to be discharged to itself or to "ground"?
To discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. Whether there is also a connection to some "ground" makes no difference to the process.
