Which of the following is NOT typically a type of protective equipment on a distribution line?

In the context of distribution lines, protective equipment is specifically designed to safeguard the electrical system and enhance reliability by preventing damage during fault conditions or abnormal operations.

Fused cut-out switches serve as disconnect switches that contain fuses which can interrupt the circuit when excessive current is detected, effectively reducing the risk of equipment damage during faults.

Reclosers are automated devices that are designed to temporarily interrupt power upon detecting a fault and, after a preset time, attempt to reconnect the power. This functionality allows the system to ride through transient faults while still providing protection to the distribution line.

Sectionalizers are devices that work in conjunction with reclosers to isolate a faulted section of the line after multiple operations of the recloser. They play a key role in maintaining the reliability and safety of the distribution system.

Contrastingly, transformers are not a protective device. Instead, they serve a primary function of stepping voltage levels up or down for efficient power distribution. While essential to the operation of the electrical grid, transformers do not provide protective functions like isolating or interrupting circuits during faults or other abnormal conditions. Therefore, they do not fit into the category of protective equipment characterized by devices designed for fault management and circuit protection, making this the correct choice for
