6 FAQs about [Substation capacitor explosion]

What is engineering failure analysis for capacitor explosions with overloading power transformers?

A new methodology is proposed for the Engineering failure Analysis for capacitors explosions with overloading power transformers condition, the individual and system assessment with an international standard review is developed for a better understanding in the solution proposal.

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.

What causes a capacitor to fail?

Capacitors operated at extreme hot conditions can fail due to excessive temperature. The excessive heat can be due to high ambient temperature, radiated heat from adjacent equipment, or extra losses. 4. Ferroresonance The capacitor banks tend to interact with the source or transformer inductance and produce ferroresonance.

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.

Why do capacitor units fail in a filter bank?

In the filter banks, the capacitor units are connected in series with inductors. Sometimes the voltage across the capacitor units exceeds the design values. In such circumstances, the capacitor units fail catastrophically due to inadequate voltage rating. 2. Fuse blowing

What happens if an internal series group of a capacitor fails?

When an internal series group of a capacitor unit fails, the voltage on the remaining internal series groups in the string increases. It is desirable to remove the bank from service when the voltage applied to the remaining internal series groups exceeds 110% of their rated voltage.
