What is the high side coil voltage for a transformer with a rating of 7620/13200Y-120/240?

The high side coil voltage of a transformer is identified by the voltage rating assigned to its primary or high voltage side. In this case, the transformer is rated at 7620/13200Y-120/240.

When examining this specification, the high side coil of the transformer refers to the voltage ratings of 7620 volts and 13200 volts. These represent the transformer’s primary side, which is connected to the power source. The designation of "13200Y" indicates that the transformer can accept a line-to-line voltage of 13200 volts, while the "7620" refers to the line-to-ground voltage in a wye configuration, which is a standard way of expressing transformer ratings.

Therefore, among the choices provided, 7620 volts represents one of the high side voltage configurations for the transformer. This matches the established terminology for transformers, wherein the high side voltage is critical for understanding how the transformer operates and what levels are needed on the primary side to ensure proper step-down functionality for the secondary outputs, which are noted as 120 volts and 240 volts.

In summary, the identification of 7620 volts as the high side coil voltage is aligned with transformer rating practices, confirming it as the correct answer.
