Multiple Choice

Power transformers may or may not have load tap changers.

Voltage regulation in power transformers is not fixed; it depends on design needs. A load tap changer lets the transformer adjust its voltage while it’s energized to keep the output steady as load or source voltage changes. Because this capability is optional and chosen based on system requirements, some transformers include an LTC, while others do not. In practice, large substations or networks with tight voltage control may employ OLTCs, whereas many distribution transformers use fixed or off‑load taps without an LTC. The best choice captures this variability: they may or may not have a load tap changer.
