Where would you typically read the output voltage during the testing of a step regulator?

The output voltage of a step regulator is typically read at the Potential Test Terminals. These terminals are specifically designed for testing and monitoring voltage output, providing a safe and accessible point for accurate measurement. This measurement is crucial for ensuring the regulator is functioning correctly and the output voltage is within the desired range.

The Potential Test Terminals allow linemen or technicians to connect their voltage meters without disrupting the regular operation of the regulator. By using this point for voltage readings, it ensures that the testing process aligns with safety protocols and operational efficiency. This is preferable to other points, such as the input terminals or the main control panel, which may not deliver a direct or accurate reading of the output voltage due to factors like voltage drop or internal circuitry.

The safety disconnect, while important for isolating the equipment during maintenance, is not intended for voltage measurements and typically does not reflect the regulator's operational output.
