What is the primary function of an oil switch in an electrical distribution line?

• A. To increase voltage levels
• B. To manually operate a switch to disconnect electric loads
• C. To improve energy efficiency
• D. To protect against voltage spikes

Answer: (B)

The primary function of an oil switch in an electrical distribution line is to manually operate a switch to disconnect electric loads. Oil switches are designed to provide reliable interruption of current under load, which means they can safely isolate sections of the electrical system for maintenance or in the event of a fault. The use of oil as an insulating medium also allows these switches to handle high voltages and currents effectively while ensuring safe and reliable operations. Oil switches are typically employed in power distribution systems because they facilitate maintenance without requiring extensive downtime and help maintain system reliability. The manual operation aspect is crucial for safety, enabling operators to isolate equipment and conduct necessary repairs or inspections without risking electric shock or other hazards associated with energized lines. Energy efficiency, voltage level increase, or protection against voltage spikes, while relevant aspects of electrical distribution management, do not describe the primary function of an oil switch. Instead, they pertain to strategies and devices focused on power quality and maintaining operational performance under various conditions.
