Multiple Choice

A special type of transformer is the ______ transformer, used for measurement of electrical quantities and for control purposes.

Measuring electrical quantities and feeding control circuits requires a device that safely lowers the voltage or current to levels suitable for meters and relays while providing electrical isolation from the high-power circuit. This role is filled by instrument transformers. They are designed specifically for measurement and control applications, not for transferring power. Within this category, potential transformers step down voltages for metering and relays, and current transformers do the same for currents. Power transformers, on the other hand, are intended primarily to transfer electrical power between circuits and are not used primarily for measurement or control.

A special type of transformer is the ______ transformer, used for measurement of electrical quantities and for control purposes.
