What voltage does the utility company deliver electrical power to the manufacturing building site?

The utility company typically delivers electrical power to commercial and manufacturing sites in standardized voltages that adhere to industry norms and local infrastructure capabilities. A common voltage level for three-phase electrical power that utilities provide is 12.47 kV. This voltage is prevalent because it strikes a balance between efficiency and manageability for the electrical loads found in manufacturing environments.

Using 12.47 kV allows for effective transmission of power over longer distances with reduced losses, making it a practical choice. This voltage level is often chosen due to its compatibility with many industrial applications and the existing transformer-to-distribution networks in various areas.

The other voltage options, while they may represent other hypothetical configurations, do not typically reflect the standard practices for utility delivery in many regions; thus, they are less applicable in this context.
