Oil filled capacitors typically have a lower capacity compared to electrolytic capacitors, but they possess a higher?

Oil-filled capacitors are known for their ability to handle higher voltages compared to electrolytic capacitors. This characteristic is often attributed to the insulating properties of the oil, which provides excellent dielectric strength, allowing the capacitor to operate safely at elevated voltage levels without breaking down. This makes oil-filled capacitors particularly valuable in applications where high voltage stability is essential, such as in power transmission and distribution systems.

In contrast, while electrolytic capacitors are designed for higher capacitance values and are often used in applications requiring substantial energy storage, they typically have lower voltage ratings, making them more susceptible to failure if exposed to voltages above their rated limits. Hence, the advantage of oil-filled capacitors in terms of voltage rating highlights their robust performance in demanding electrical environments.
