The industrial use transformer that normally has 240 V or 480 V primary and a 120 V secondary is called a(n) _____ transformer.
A) auto
B) distribution
C) isolation
D) control
Industrial Use
Refers to applications and activities involving manufacturing, production, and large-scale operations where equipment and machinery are used.
Control Transformer
A common type of isolation transformer generally used to change line voltage of 240 or 480 volts into 120 volts to operate motor-control equipment.
Auto
Refers generally to automobiles or the automation of systems, indicating self-operation or control of devices without direct human intervention.
- Identify the distinctions among transformer categories based on their operational roles and design characteristics.
- Comprehend the employment of transformers within a variety of contexts, with a particular emphasis on power distribution and control mechanisms.

Final Answer :
D
Explanation :
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.
