What is the voltage for DWP Transmission lines?

The voltage for DWP (Los Angeles Department of Water and Power) Transmission lines is indeed within the range of 138 kV and 230 kV. These high voltages are necessary for efficient transmission of electricity over long distances, minimizing energy losses during transportation. The higher the voltage, the lower the current for the same amount of power, which reduces resistive losses due to the resistance of the transmission lines.

In a utility context, the transmission system is typically designed to handle these high kV levels to facilitate the bulk passing of electricity from generation sites to substations. Other options, such as 34.5 kV and 4.8 kV, usually pertain to distribution systems rather than transmission, which operate at significantly lower voltages. The mention of 2516 PSI does not pertain to electrical transmission at all but rather to pressure, which is irrelevant in this context. This further confirms that the correct answer aligns with the specifications of transmission voltage levels commonly used in utility systems.
