Shunt capacitor banks are essential for reactive power compensation, ensuring voltage stability, and reducing system losses. These banks consist of multiple units with components in series and parallel. A few component failures do not immediately affect the safe operation of the capacitor bank, but component breakdown can lead to voltage redistribution.

Visual inspection is another effective diagnostic tool for assessing capacitor health. Observable signs like bulging, swelling, or electrolyte leakage are clear indicators of internal failure modes, often resulting from excessive pressure within the casing.
Yes, it is possible for a capacitor to fail without any visible signs. Sometimes, a capacitor may have internal issues or damage that is not immediately apparent from its exterior.
A capacitance value significantly below the nominal rating is indicative of dielectric failure or deterioration, necessitating replacement. Visual inspections should complement these tests, particularly in high-power circuits where capacitors in power supply filter sections are more susceptible to failure.

Mica and tantalum capacitors are more likely to fail in the early period of use (early failure), while aluminum electrolytic capacitors are more likely to experience wear-out failure due to aging use. In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal.
Such failures can be avoided with preventive maintenance action such as replacing the capacitor. For film capacitors, the typical failure mode is capacitance decrease due to self-healing, so it is possible to diagnose the life expectancy by understanding the capacitance change.
