On a mild spring day, a transmission line trips. The line then trips again when energized. Which of the following is least likely to be the problem?

On a mild spring day, a transmission line trips. The line then trips again when energized. Which of the following is least likely to be the problem?

• A. Vandalism
• B. Overload
• C. Equipment failure
• D. Sabotage

Answer: (B)

The scenario describes a situation where a transmission line initially trips and then trips again after being re-energized. This kind of behavior typically points to issues related to equipment malfunctions or external interference rather than a capacity issue. Overload occurs when a transmission line carries more power than it is rated for, causing it to trip to protect itself from damage. However, given that it’s a mild spring day, the likelihood of the transmission line being overloaded is quite low. Seasonal factors usually lead to lower demands for electricity, thus reducing the chance of overload conditions. Vandalism and sabotage typically involve intentional acts that could lead to a line tripping or failing, and although they are concerns, their direct relevance to the situation of the line tripping multiple times is less consistent. Equipment failure, on the other hand, is a common cause of such incidents, particularly when a line trips again after being re-energized, indicating a failure within the equipment itself or at a connection point. Therefore, overload is the least likely cause in this specific scenario.
