How is the high side coil voltage represented in electrical engineering standards?

In electrical engineering standards, the representation of high side coil voltage typically aligns with common voltages used in high-voltage distribution systems. The value of 7200 volts is commonly referenced as a standard for systems in North America, particularly for distribution transformers and overhead power lines.

The 7200 volts designation is particularly important when discussing the primary side of a transformer or the higher voltage levels in three-phase systems. It fits within the range of high voltage standards that utility companies utilize to ensure effective transmission of electricity across long distances with minimal losses.

By contrast, other values like 220 volts and 480 volts are more associated with lower voltage levels for residential and industrial applications, making them unsuitable for identifying high side coil voltages. The 9000 volts option exceeds typical standards for most utility applications and is less common in general discussions about high side systems. Therefore, the selection of 7200 volts accurately reflects the industry norms for high voltage coil representation.
