If a 480 - 240-volt transformer is connected to a circuit with a voltage of 518, what will be the secondary line voltage without compensating taps?

To determine the secondary line voltage of a transformer, it's essential to understand the transformer's turns ratio and how it relates the primary and secondary voltages.

In this case, a 480 - 240-volt transformer typically has a primary voltage of 480 volts and a secondary voltage of either 240 volts (line to line) or 120 volts (line to neutral in a split-phase system). The transformer's function is to step down or step up voltages based on the turns ratio.

When a transformer is supplied with a primary voltage of 518 volts instead of the nominal 480 volts for which it is rated, the secondary voltage will scale accordingly.

To find the secondary voltage when connected to the circuit voltage of 518 volts, you can use the following relationship based on the turns ratio:

1. The turns ratio from primary (480) to secondary (240) is 2:1 - meaning that for every 2 volts on the primary side, there are 1 volt on the secondary side.

2. Therefore, if the primary voltage is increased to 518 volts, the secondary voltage can be calculated as follows:

\text{Secondary Voltage} = \frac{240 \text{ volts}}{
