Which voltage is NOT considered distribution voltage?

Which voltage is NOT considered distribution voltage?

• A. 4 kV
• B. 11 kV
• C. 13 kV
• D. 27 kV

Answer: (B)

Distribution lines are the medium-voltage feeders that carry power from substations to neighborhoods and businesses. They sit in the lower end of the voltage spectrum used by the utility, typically a few kilovolts up to the tens of kilovolts, depending on the system. In many grids, 4 kV and voltages around 13 kV or 27 kV are common for distribution feeders, while transmission voltages are much higher and used for long-distance bulk power. The 11 kV level isn’t a standard distribution feeder in many utility practices; it’s more often associated with subtransmission or other intermediate parts of the system rather than the distribution feeders that directly serve customers. So, among the options, 11 kV is not considered distribution voltage, while 4 kV, 13 kV, and 27 kV are.
