6 FAQs about [Common problems and solutions of explosion-proof capacitors]

What are some of the failure problems associated with capacitor banks?

Some of the failure problems associated with capacitor banks are already known since they happen often. A few of the failures are traceable to the original source and sometimes that may be difficult to do. In many instances, the final result of a failure may be a catastrophic explosion of the capacitor into pieces or fire.

Why do capacitors fail?

These defects have been observed in different areas of the capacitors. It should be noted that inappropriate assembly process (i.e., excessive thermal stress) whether it is internal to the manufacturer or during the assembly of the capacitors, is considered as an extra stress factor that weakens the capacitors’ reliability.

What causes a hermetically sealed capacitor to fail?

Fatigue in the leads or mounting brackets can also cause a catastrophic failure. The altitude at which hermetically sealed capacitors are to be operated will control the voltage rating of the capacitor. As the barometric pressure decreases so does the terminal "arc-over" susceptibility increase.

What are the different types of capacitor problems?

What are the common failure modes of capacitors?

What happens if a capacitor bank is not damped?

The capacitor banks tend to interact with the source or transformer inductance and produce ferroresonance. This can produce undamped oscillations in the current or voltage, depending on the type of resonance. If the system is not adequately damped, then there is a possibility of capacitance or transformer failure.
