What aspect is NOT typically enhanced through periodic maintenance of electrical systems?

Periodic maintenance of electrical systems is primarily aimed at ensuring that the system operates safely, reliably, and efficiently. Enhancing system safety involves regular inspections and repairs to prevent accidents and maintain compliance with safety standards. System reliability is improved through preventive measures that reduce the likelihood of failures and unplanned downtime. Efficiency is targeted by maintaining equipment and making necessary adjustments that optimize energy consumption and performance.

In contrast, system complexity does not benefit from maintenance in the same way. Rather, complexity typically refers to the intricacy of the system's design, architecture, or operational processes. Maintenance does not simplify or complicate the inherent design of the system; instead, it ensures that the existing setup functions as intended. Therefore, periodic maintenance aims to enhance safety, reliability, and efficiency while not influencing the complexity of the electrical system.
