Is it true that a control transformer can allow for separate lines for power and control devices?

A control transformer is designed to step down voltage levels while providing isolation between the control and power sections of a circuit. One of its key functions is to supply control devices with a lower voltage power source, typically 120 VAC or similar, while allowing the power devices to operate at a higher, potentially hazardous voltage level. This isolation ensures that low-voltage control circuits can be operated safely without the risk of exposure to higher voltage levels.

The assertion that a control transformer can allow for separate lines for power and control devices is indeed true. By isolating the control circuit from the power circuit, a control transformer enhances safety and provides more flexibility in the design of control systems. It allows for the use of different voltages for control and power devices without mixing them on the same circuitry, which is a critical design practice in motor control applications.

Since the correct understanding is that control transformers facilitate the separation of power and control devices safely, the statement suggesting that the answer is false overlooks this fundamental aspect of what control transformers are designed to achieve.
