What is the voltage of the high side coil mentioned?

The high side coil mentioned in the question is typically associated with the primary side of a transformer in power distribution systems. In many utility applications, the voltage levels on the high side coils are substantial to ensure efficient power transmission over long distances.

The voltage of 7200 volts aligns with standard primary transformer voltages commonly used in distribution systems. This level allows for effective energy transmission while balancing insulation requirements and minimizing line losses. It’s a configuration that supports the high-side operation of transformers that step down voltage levels for distribution to residential or commercial use.

Options like 480 volts and 2500 volts represent lower voltage levels that might be used in secondary sides or different applications, while 12000 volts would be a higher standard likely not used in most common high side configurations in typical distribution settings. Thus, the choice of 7200 volts is consistent with commonly accepted standards in the electrical industry for high side coil applications.
