What is the primary purpose of routing power through transformers at a water treatment facility?

• A. To reduce the voltage
• B. To make switching to the facility electrical grid easier
• C. To increase the voltage
• D. For safety reasons

Answer: (A)

The main idea is that transformers change the voltage to match what the on-site equipment needs. At a water treatment plant, power typically enters at a higher voltage from the grid to keep transmission losses down. The equipment—pumps, motors, and control systems—usually runs at lower, standard voltages. A transformer steps the voltage down to those levels, making operation safe and ensuring insulation and protective devices are appropriately sized. Increasing the voltage would not serve the on-site loads, and while stepping voltage down supports safer operation, that's a consequence of providing the correct voltage rather than the primary goal. The notion of making switching to the grid easier isn’t the main purpose of routing power through transformers.
