Oil switches are most commonly used for capacitor switching, street lighting control, and automatic disconnect applications. This is due to their ability to handle high currents and voltages while providing a reliable means of switching under load. In capacitor switching, oil switches help in managing reactive power and maintaining system stability by connecting and disconnecting capacitors in response to demand. For street lighting control, they automate the operation of lighting systems, allowing for efficient energy use and management.

The automatic disconnect function is critical for ensuring safety in electrical systems, enabling circuits to be isolated quickly in case of faults or maintenance needs. The use of oil in these switches provides excellent insulation and cooling properties, making them suitable for high-capacity applications where heat dissipation is necessary.

In contrast, the other options involve less relevant functionalities for oil switches. For example, voltage regulation and surge protection primarily pertain to devices designed to manage voltage levels rather than switching. Similarly, energy storage and distribution refer to techniques and devices such as batteries and transformers, which do not inherently utilize oil switches. Lastly, current sensing and analysis involve measurement instruments that are not the primary functions of oil switches.
