Q: What is the primary purpose of a transformer's protective devices?

To prevent damage to the transformer and the connected equipment. — Protective devices, such as fuses and relays, are designed to detect faults and isolate the transformer to prevent it from being damaged and to protect the connected system.

Q: Which of the following is a common protective device used for transformers?

Overcurrent relay — Overcurrent relays are frequently used to protect transformers by detecting excessive current flow caused by faults like short circuits.

Q: What is the purpose of a turns ratio test?

To verify the correct turns ratio of the transformer windings. — The turns ratio test confirms that the number of turns in the primary and secondary windings are as designed, which is essential for proper voltage transformation.

Q: What does a high-potential (hipot) test measure?

The insulation strength of the transformer windings.
