What is one consequence of improper adjustment of a transformer?

One consequence of improper adjustment of a transformer is an increased safety risk. When a transformer is not properly adjusted, it may operate outside of its designed parameters, leading to issues such as overheating, insulation breakdown, or even electrical arcs. These conditions can pose significant hazards not only to the equipment itself but also to personnel working nearby. Improper adjustments can create excessive load on the transformer, causing it to fail and potentially leading to fires or electrical incidents that could harm workers or damage other equipment.

In contrast, operational efficiency, while also negatively impacted by improper adjustments, does not directly create safety risks in the same immediate manner. Increased system stability and enhanced voltage regulation would be goals of proper transformer adjustment, but when adjustments are made incorrectly, these benefits can be lost, leading predominantly to safety concerns rather than improved stability or regulation.
