Potential transformers are connected in __________ with the line.

Potential transformers are connected in __________ with the line.

• A. Series
• B. Parallel
• C. Magnetically
• D. Grounded

Answer: (B)

Potential transformers are connected in parallel with the line. This configuration allows the transformer to measure the voltage of the high-voltage line accurately without interrupting the flow of electricity. By connecting in parallel, the potential transformer provides a reduced voltage that is safe for measurement and monitoring equipment while still reflecting the line voltage. This setup is essential for protective relaying, metering, and monitoring purposes, as it allows for precise voltage readings that can be used to manage and protect electrical systems. When a potential transformer is connected parallelly, it ensures that the primary circuit operates normally, while the transformer produces a secondary voltage proportional to the line voltage for analysis and control. This is a common practice in electrical engineering to ensure that live systems can be safely monitored and controlled.
