Some larger transformers include ____ controlled fans that circulate air through the radiators to further assist in heat removal.
A) thermostatically

D) alarm-

Question

Quizplus · Accepted Answer

Thermostatically controlled fans would provide the most efficient method of circulating air through the radiators as they would only activate when needed based on the temperature of the transformer, helping to conserve energy. The other options (remote-, electrically, and alarm-) do not provide a specific method of controlling the operation of the fans for optimal heat removal.
