Often, burning ceramic capacitors are underrated in the electronics industry although they may pose a substantial problem. RoodMicrotec offers effective solutions for this problem. Find out more about how we deal with reasons and potential dangers and which methods we use to detect crack formations unequivocally.
The main reason for a burning or even exploding capacitor bank is the liquid-filled capacitors, or the plastic parts that are combustible. If the temperature rises, the capacitor can cause a fire, a life-threatening situation, and economic loss.
Moreover, the capacitor lifetime depends directly on the operating temperature hence an overheating will lead to a faster aging. The main reason for a burning or even exploding capacitor bank is the liquid-filled capacitors, or the plastic parts that are combustible.
The dangers of burning ceramic capacitors are numerous and varied. In addition to potential damage to the electronic circuit, fires can occur that may cause considerable damage to property and even personal injury.
Hence, we are highly recommend to add Detuned Reactors (7%,14% & 5.67%) in the capacitor banks as a safety precaution. Routine Test has been carried out in compliance with the requirements of IEC 61921,Clause 11.9 which applies to LV Switchgear and control gear assemblies.
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.
No, capacitor explosions are comparatively uncommon. To reduce the danger of failure, capacitors are constructed with safety measures that adhere to standards. The likelihood of a capacitor bursting is significantly decreased by following appropriate usage instructions and operating circumstances.
