The voltage in overhead power lines in residential areas in the United States is typically 7,200 volts before it is stepped down to 120 volts for household use. The discussion also raises questions about the primary inductance of distribution transformers responsible for this voltage reduction. While specific inductance values were not provided, it is acknowledged that the inductance is significant due to the nature of transformer design. For further information, resources such as HowStuffWorks can provide additional insights into power distribution systems.
PREREQUISITESElectrical engineers, utility workers, students studying electrical engineering, and anyone interested in understanding the power distribution system in the United States.
cuallito said:1) What's the voltage in the overhead power lines in residential areas? Basically how many volts is it before it gets stepped down to 120 for your house?
2) What's the typical primary inductance of a distribution transformer that does the stepping down?
