It represents the amount of electrical charge the capacitor can store when a specified …
It may occur due to inadequate ventilation, loose connections, bad design, or the overvoltage during lower demand period. Moreover, the capacitor lifetime depends directly on the operating temperature hence an overheating will lead to a faster aging.
This is especially true when film capacitors are used in alternating current circuits in which overheating can cause combustion failure. • Solid Tantalum Capacitors: Overheating due to current surges can result in material disintegration and dormant damage to the dielectric over time in solid tantalum capacitors.
To be specific, overheating decomposes the electrolyte and generates a build-up of gas that increases internal pressure. Note that an electrolytic capacitor is a polarized capacitor that uses an electrolyte to achieve a larger capacitance than other types of capacitors.
Moreover, the capacitor lifetime depends directly on the operating temperature hence an overheating will lead to a faster aging. Overheating of capacitor banks is a common problem in reactive power control systems, and these systems are an essential part of electric distribution and transmission.
