B) distribution
C) isolation
D) control

Question

Quizplus · Accepted Answer

Control transformers are specifically designed to provide a high degree of secondary voltage stability during a brief period of overload condition (also known as 'inrush current'). These transformers are typically used in industrial environments to step down the voltage to a level suitable for the control circuits, which commonly operate at 120V. Hence, a transformer with a 240V or 480V primary and a 120V secondary is referred to as a control transformer.
